You can install python packages using python3.6 -m pip install [Package_to_install] straight away.
I use PipEnv for working in different environments with different python versions.
the usage would be something like pipenv --python 3.X and it will install that version of python if its not installed.
It also makes things really helpful if you are collaborating with other developers, because it creates a PipFile (alt to requirements.pip) which will contain the version of python used for the project so all developers will use the same version of python on a project without doing any prep work.
If you don't want to use pipenv you can use pip3.5 or create a python3.5 environment like virtualenv [NAME] --python=/usr/lib/python3.5 and then install the package using pip install somepackage
This will help you fix the above problem
You need to add following personal package repository:
sudo add-apt-repository ppa:deadsnakes/ppa
Check for updates
sudo apt-get update
install python using following command
sudo apt-get install python3.6
It was easy. I just changed my default python3 version:
sudo gedit ~/.bashrc alias python3="python3.6"
Now I can install the packages using python3.6 with
-m pip install 'packagenae'
Whenever I am trying to install any package using pip, I am getting this import error:
guru#guru-notebook:~$ pip3 install numpy
Traceback (most recent call last):
File "/usr/bin/pip3", line 9, in <module>

# we didn't install the actual entry point from setup.py, don't use the
# pkg_resources API.
from pip import main
if __name__ == '__main__':
sys.exit(main())
It was working fine earlier, I am not sure why it is throwing this error.
I have searched about this error, but can't find anything to fix it.
Please let me know if you need any further detail, I will update my question.
You must have inadvertently upgraded your system pip (probably through something like sudo pip install pip --upgrade)
pip 10.x adjusts where its internals are situated. The pip3 command you're seeing is one provided by your package maintainer (presumably debian based here?) and is not a file managed by pip.
You can read more about this on pip's issue tracker
You'll probably want to not upgrade your system pip and instead use a virtualenv.
To recover the pip3 binary you'll need to sudo python3 -m pip uninstall pip && sudo apt install python3-pip --reinstall.
If you want to continue in "unsupported territory" (upgrading a system package outside of the system package manager), you can probably get away with python3 -m pip ... instead of pip3.
We can clear the error by modifying the pip file.
Check the location of the file:
$ which pip
path -> /usr/bin/pip
Go to that location(/usr/bin/pip) and open terminal
Enter: $ sudo nano pip
You can see:
import sys
from pip import main
if __name__ == '__main__':
sys.exit(main())
Change to:
import sys
from pip import __main__
if __name__ == '__main__':
sys.exit(__main__._main())
then ctrl + o write the changes and exit
Hope this will do!!
For Ubuntu family, Debian, Linux Mint users
Thanks to Anthony's explanation above, you can retain your original system pip (in /usr/bin/ and dist-packages/) and remove the manually-installed pip (in ~/.local/) to resolve the conflict:
$ python3 -m pip uninstall pip
Ubuntu/Debian pip v8.1.1 (16.04) from python3-pip debian package (see$ pip3 -V) shows the same search results as the latest pip v10.0.1, and installs latest modules from PyPI just fine. It has a working pip command (already in the $PATH), plus the nice --user option patched-in by default since 2016. Looking at pip release notes, the newer versions are mostly about use-case specific bug fixes and certain new features, so not everyone has to rush upgrading pip just yet. And the new pip 10 can be deployed to Python virtualenvs, anyway.
But regardless of pips, your OS allows to quickly install common Python modules (including numpy) with APT, without the need for pip, for example:
$ sudo apt install python3-numpy python3-scipy (with system dependencies)
$ sudo apt install python3-pip (Debian-patched pip, slightly older but it doesn't matter)
Quick apt syntax reminder (please see man apt for details):
$ sudo apt update (to resync Ubuntu package index files from up-to-date sources)
$ apt search <python-package-name> (full text-search on all available packages)
$ apt show <python-package-name> (displays the detailed package description)
$ sudo apt install <python-package-name>
Package names prefixed with python- are for Python 2; and prefixed with python3- are for Python 3 (e.g. python3-pandas). There are thousands, and they undergo integration testing within Debian and Ubuntu. Unless you seek to install at per-user level (pip install --user option) or within virtualenv/venv, apt could be what you needed. These system packages are accessible from virtual envs too, as virtualenv will gracefully fall back to using system libs on import if your envs don't have given copies of modules.
Your custom-installed (with pip --user) per-user modules in ~/.local/lib will override them too.
Note, since this is a system-wide installation, you'd rarely need to remove them (need to be mindful about OS dependencies). This is convenient for packages with many system dependencies (such as with scipy or matplotlib), as APT will keep track and provide all required system libs and C extensions, while with pip you have no such guarantees.
In fact, for system-wide Python packages (in contrast to per-user, home dir level, or lower), Ubuntu expects using the APT package manager (rather than sudo pip) to avoid breaking OS: sudo pip3 targets the very same /usr/lib/python3/dist-packages directory where APT stores OS-sensitive modules. Recent Debian/Ubuntu releases depend heavily on Python 3, so its pre-installed modules are managed by apt and shouldn't be changed.
So if you use pip3 install command, please ensure that it runs in an isolated virtual dev environment, such as with virtualenv (sudo apt install python3-virtualenv), or with Python3 built-in (-m venv), or at a per-user level (--user pip option, default in Ubuntu-provided pip since 2016), but not system-wide (never sudo pip3!), because pip interferes with the operation of the APT package manager and may affect Ubuntu OS components when a system-used python module is unexpectedly changed. Good luck!
P. S. All the above is for the 'ideal' solution (Debian/Ubuntu way).
If you still want to use the new pip3 v10 exclusively, there are 3 quick workarounds:
simply open a new bash session (a new terminal tab, or type bash) - and pip3 v10 becomes available (see pip3 -V). debian's pip3 v8 remains installed but is broken; or
the command $ hash -d pip3 && pip3 -V to refresh pip3 pathname in the $PATH. debian's pip3 v8 remains installed but is broken; or
the command $ sudo apt remove python3-pip && hash -d pip3 to uninstall debian's pip3 v8 completely, in favor of your new pip3 v10.
Note: You will always need to add --user flag to any non-debian-provided pip, unless you are in a virtualenv! (it deploys python packages to ~/.local/, default in debian/ubuntu-provided python3-pip and python-pip since 2016). Your use of pip 10 system-wide, outside of virtualenv, is not really supported by Ubuntu/Debian. Never sudo pip3!

resolved in one step only.
I too faced this issue, But this can be resolved simply by 1 command without bothering around and wasting time and i have tried it on multiple systems it's the cleanest solution for this issue. And that's:
For python3:- sudo python3 -m pip uninstall pip && sudo apt install python3-pip --reinstall.
By this , you can simply install packages using pip3. to check use pip3 --version.
For older versions, use : sudo python -m pip uninstall pip && sudo apt install python-pip --reinstall.
By this, now you can simply install packages using pip. to check use pip --version.
Use python -m pip install instead of pip install
Example:
python -m pip install --user somepackage
python3 -m pip install --user somepackage
The pip (resp. pip3) executable is provided by your distro (python-pip package on Ubuntu 16.04) and located at /usr/bin/pip.
Therefore, it is not kept up-to date with the pip package itself as you upgrade pip, and may break.
If you just use python -m pip directly, e.g. as in:
python -m pip install --user somepackage
python3 -m pip install --user somepackage
it goes through your Python path, finds the latest version of pip and executes that file.
It relies on the fact that file is executable through import, but that is a very standard type of interface, and therefore less likely to break than the hackier Debian script.
Then I recommend adding the following aliases to your .bashrc:
pip() ( python -m pip "$#" )
pip3() ( python3 -m pip "$#" )
The Ubuntu 18.04 /usr/bin/pip3 file does:
from pip import main
and presumably main was removed from pip at some point which is what broke things.
The breaking pip commit appears to be: 95bcf8c5f6394298035a7332c441868f3b0169f4 "Move all internal APIs to pip._internal" which went into pip 18.0.
Tested in Ubuntu 16.04 after an update from pip3 9.0.1 to 18.0.
pyenv
Ultimately however, for serious Python development I would just recommend that you install your own local Python with pyenv + virtualenv, which would also get around this Ubuntu bug: https://askubuntu.com/questions/682869/how-do-i-install-a-different-python-version-using-apt-get/1195153#1195153
You can resolve this issue by reinstalling pip.
Use one of the following command line commands to reinstall pip:
Python2:
python -m pip uninstall pip && sudo apt install python-pip --reinstall
Python3:
python3 -m pip uninstall pip && sudo apt install python3-pip --reinstall
Check if pip has been cached on another path, to do so, call $ which pip and check that the path is different from the one prompted in the error, if that's the case run:
$ hash -r
When the cache is clear, pip will be working again.

I'm running on a system where I have sudo apt but no sudo pip. (And no su access.) I got myself into this same situation by following the advice from pip:
You are using pip version 8.1.1, however 18.0 is available. You should consider upgrading via the 'pip install --upgrade pip' command.
None of the other fixes worked for me, because I don't have enough admin privileges. However, a few things stuck with me from reading up on this:
I shouldn't have done this. Sure, pip told me to. It lied.
Using --user solves a lot of issues by focusing on the user-only directory.
So, I found this command line to work to revert me back to where I was. If you were using a different version than 8.1.1, you will obviously want to change that part of the line.
python -m pip install --force-reinstall pip==8.1.1 --user
That's the only thing that worked for me, but it worked perfectly!
I met the same problem on my Ubuntu 16.04 system. I managed to fix it by re-installing pip with the following command:
curl https://bootstrap.pypa.io/get-pip.py | sudo python3
Recover with python3 -m pip install --user pip==9.0.1 (or the version that worked)
Same thing happened to me on Pixelbook using the new LXC (strech). This solution is very similar to the accepted one, with one subtle difference, whiched fixed pip3 for me.
sudo python3 -m pip install --upgrade pip
That bumped the version, and now it works as expected.
I found it here ... Python.org: Ensure pip is up-to-date
The commands above didn't work for me but those were very helpful:
sudo apt purge python3-pip
sudo rm -rf '/usr/lib/python3/dist-packages/pip'
sudo apt install python3-pip
cd
cd .local/lib/python3/site-packages
sudo rm -rf pip*
cd
cd .local/lib/python3.5/site-packages
sudo rm -rf pip*
sudo pip3 install jupyter
In ubuntu 18.04.1 Bionic Beaver, you need to log out and log back in (restart not necessary) to get the proper environment.

For Python version 2.7 #Anthony solution works perfect, by changing python3 to python as follows:
sudo python -m pip uninstall pip && sudo apt install python-pip --reinstall
What worked for me to fix the error with using pip3 was:
sudo cp -v /usr/local/bin/pip3 /usr/bin/pip3
Everything works:
demon#UbuntuHP:~$ pip -V
pip 10.0.1 from /usr/local/lib/python3.5/dist-packages/pip (python 3.5)
demon#UbuntuHP:~$ pip2 -V
pip 10.0.1 from /home/demon/.local/lib/python2.7/site-packages/pip (python 2.7)
demon#UbuntuHP:~$ pip3 -V
pip 10.0.1 from /usr/local/lib/python3.5/dist-packages/pip (python 3.5)
Maybe the new 10.0.1 version of pip doesn't update the binary in /usr/bin ? (which seems it does not)
EDIT: the same issue occurs in Ubuntu 18.04. The best solution I've found is to symlink the pip binaries from /home/<user/.local/bin to /usr/local/bin or /usr/bin (depending on your preference), as follows:
ln -sv /home/<user>/.local/bin/pip /usr/local/bin/pip
ln -sv /home/<user>/.local/bin/pip2 /usr/local/bin/pip2
ln -sv /home/<user>/.local/bin/pip2.7 /usr/local/bin/pip2.7
ln -sv /home/<user>/.local/bin/pip3 /usr/local/bin/pip3
ln -sv /home/<user>/.local/bin/pip3.6 /usr/local/bin/pip3.6
NOTE: replace <user> with your current running user
The associated versions (latest) are in:
Version 3.6:
/home/demon/.local/lib/python3.6/site-packages/pip (python 3.6)
Version 2.7:
/home/demon/.local/lib/python2.7/site-packages/pip (python 2.7)
Trick and works too
sudo -H pip install lxml
I had this same error, but python -m pip was still working, so I fixed it with the nuclear option sudo python -m pip install --upgrade pip. It did it for me.
For what it's worth, I had the problem with pip (not pip2 or pip3):
$ pip -V
Traceback (most recent call last):
File "/usr/bin/pip", line 9, in <module>
from pip import main
ImportError: cannot import name main
$ pip2 -V
pip 8.1.1 from /usr/lib/python2.7/dist-packages (python 2.7)
$ pip3 -V
pip 8.1.1 from /usr/lib/python3/dist-packages (python 3.5)
Somehow (I can't remember how) I had python stuff installed in my ~/.local directory. After I removed the pip directory from there, pip started working again.
$ rm -rf /home/precor/.local/lib/python2.7/site-packages/pip
$ pip -V
pip 8.1.1 from /usr/lib/python2.7/dist-packages (python 2.7)
Is something wrong with the packages, when it generating de file /usr/bin/pip,
you have to change the import:
from pip import main
to
from pip._internal import main
That solves the problem, I'm not sure why it generated, but it saids somthing in the following issue:
After pip 10 upgrade on pyenv "ImportError: cannot import name 'main'"
You can try this:
sudo ln -sf $( type -P pip ) /usr/bin/pip
I also run into this problem when I wanted to upgrade system pip pip3 from 9.0.1 to 19.2.3.
After running pip3 install --upgrade pip, pip version becomes 19.2.3. But main() has been moved in pip._internal in the latest version, which leaves pip3 broken.
So in file /usr/bin/pip3, replace line 9: from pip import main with from pip._internal import main. The issue will be fixed, works the same for python2-pip. (Tested on Ubuntu 18.04 distribution)
According to #Vincent H.'s answer
Please run the following commands to do the fix. After running python3 -m pip install --upgrade pip, please run the following command.
hash -r pip
Source: https://github.com/pypa/pip/issues/5221
you can simply fix the pip and pip3 paths using update-alternatives
first thing you should check is your current $PATH
run echo $PATH and see is you can find /usr/local/bin which is where pip3 and pip usually are
there is a change your system is looking here /bin/pip and /bin/pip3
so i will say fix the PATH by adding to your ~/.bash_profile file so it persists
export PATH=$PATH:/usr/local/bin
and then check is its fixed with which pip and which pip3
if not then use update-alternatives to fix it finally
update-alternatives --install /bin/pip3 pip3 /usr/local/bin/pip3 30
and if you want to point pip to pip3 then
update-alternatives --install /bin/pip pip /usr/local/bin/pip3 30
I have the same problem and solved it. Here is my solution.
First, when I run pip install something, the error came out like this:
Traceback (most recent call last):
File "/usr/bin/pip3", line 9, in <module>
from pip import main
ImportError: cannot import name 'main'
So, I cd into the file /usr/bin/ and cat pip3 to see the code in it. I see this in it:
#!/usr/bin/python3
# GENERATED BY DEBIAN
import sys
# Run the main entry point, similarly to how setuptools does it, but because
# we didn't install the actual entry point from setup.py, don't use the
# pkg_resources API.
from pip import main
if __name__ == '__main__':
sys.exit(main())
And then I think that it was not in the installation path. So I cd into the python3-pip, like this:
cd /.local/lib/python3.5/site-packages/pip
P.S.: you have to cd into the right directions in your computer
Then I cat the file to see the differences(you can use other operations to see the code):
cat __main__.py
And I saw this:
from __future__ import absolute_import
import os
import sys
# If we are running from a wheel, add the wheel to sys.path
# This allows the usage python pip-*.whl/pip install pip-*.whl
if __package__ == '':
# __file__ is pip-*.whl/pip/__main__.py
# first dirname call strips of '/__main__.py', second strips off '/pip'
# Resulting path is the name of the wheel itself
# Add that to sys.path so we can import pip
path = os.path.dirname(os.path.dirname(__file__))
sys.path.insert(0, path)
from pip._internal import main as _main # isort:skip # noqa
if __name__ == '__main__':
sys.exit(_main())
So, can you see the difference? I can figure out that I have to make the file the same as the file in /usr/bin/pip3
So, I copied the code in /.local/lib/python3.5/site-packages/pip to replace the code in /usr/bin/pip3
and the problem disappear!
P.S.: pip3 or pip have no difference in this problem.
I will be happy if my solution solve your problem!
This Worked for me !
hash -r pip # or hash -d pip
Now, uninstall the pip installed version and reinstall it using the following commands.
python -m pip uninstall pip # sudo
sudo apt install --reinstall python-pip
If pip is broken, use:
python -m pip install --force-reinstall pip
Hope it helps!
I used the following code to load a module that might need install, thus avoiding this error (which I also got) - using the latest Python and latest pip with no problem
try
from colorama import Fore, Back, Style
except:
!pip install colorama
from colorama import Fore, Back, Style
import main from pip._internal
from pip._internal import main
Edit the pip code from
sudo nano /usr/bin/pip3
As #cryptoboy said - check what pip/python version you have installed
demon#UbuntuHP:~$ pip -V
demon#UbuntuHP:~$ pip2 -V
demon#UbuntuHP:~$ pip3 -V
and then check for no-needed libraries in your .local/lib/ folder.
I did backup of settings when I was migrating to newer Kubuntu and in had .local/lib/python2.7/ folder in my home directory. Installed python 3.6. I just removed the old folder and now everything works great!
On Debian you will need to update apt first....
sudo apt-get update -qq
sudo apt-get install python-pip -qq
sudo pip install pip --upgrade --quiet
sudo pip2 install virtualenv --quiet
If you skip 'sudo apt-get update -qq' your pip will become corrupt and display the 'cannot find main' error.
I want to install TensorFlow following these instructions: https://web.archive.org/web/20170627102751/https://www.tensorflow.org/versions/r0.12/get_started/os_setup#pip_installation

The directory '/Users/makotomiyazaki/Library/Caches/pip/http' or its
parent directory is not owned by the current user and the cache has
been disabled. Please check the permissions and owner of that

You must give at least one requirement to install (see "pip help

I also tried which pip3, but just I don't know if it worked...
MakotonoMacBook-ea:~ makotomiyazaki$ sudo which pip3 install --upgrade $TF_BINARY_URL
/usr/bin/install
You would need to install pip3.
On Linux, run first sudo apt update. Then the command would be: sudo apt install python3-pip
On Mac, using brew, first brew install python3
Then brew postinstall python3
Try calling pip3 -V to see if it worked.
I had this issue and I fixed it using the following steps
You need to completely uninstall python3-pip using:
sudo apt-get --purge autoremove python3-pip
Then resintall the package with:
sudo apt install python3-pip
To confirm that everything works, run:
pip3 -V
After this you can now use pip3 to manage any python package of your interest. Eg
pip3 install NumPy
Writing the whole path/directory eg. (for windows) C:\Programs\Python\Python36-32\Scripts\pip3.exe install mypackage. This worked well for me when I had trouble with pip.
its possible if you already have a python installed (pip) you could do a upgrade on mac by
brew upgrade python
Try this if other methods do not work:
brew install python3
brew link --overwrite python
brew postinstall python3
In my case, although python3-pip was already installed, it didn't recognize pip3. After reinstalling with
sudo yum reinstall python3-pip
it worked fine and recognized pip3 commands.
After yum install python3-pip, check the name of the installed binary. e.g.
ll /usr/bin/pip*
On my CentOS 7, it is named as pip-3 instead of pip3.
I downloaded pip and ran python setup.py install and everything worked just fine. The very next step in the tutorial is to run pip install <lib you want> but before it even tries to find anything online I get an error "bash: pip: command not found".
This is on Mac OS X. I'm assuming there's some kind of path setting that was not set correctly when I ran setup.py. How can I investigate further? What do I need to check to get a better idea of the exact cause of the problem?
EDIT: I also tried installing Python 2.7 for Mac in the hopes that the friendly install process would do any housekeeping like editing PATH and whatever else needs to happen for everything to work according to the tutorials, but this didn't work. After installing, running 'python' still ran Python 2.6 and PATH was not updated.
Why not just do sudo easy_install pip or if this is for python 2.6 sudo easy_install-2.6 pip?
This installs pip using the default python package installer system and saves you the hassle of manual set-up all at the same time.
This will allow you to then run the pip command for python package installation as it will be installed with the system python. I also recommend once you have pip using the virtualenv package and pattern. :)
2020 Update:
For current Debian/Ubuntu, use
apt-get install python3-pip
to install pip3.
Old 2013 answer (easy_install is now deprecated):
Use setuptools to install pip: sudo easy_install pip
(I know the above part of my answer is redundant with klobucar's, but I can't add comments yet), so here's an answer with a solution to sudo: easy_install: command not found on Debian/Ubuntu: sudo apt-get install python-setuptools
Also, for python3, use easy_install3 and python3-setuptools.
For Python 3, use apt-get install python3-pip.
First of all: try pip3 instead of pip. Example:
pip3 --version
pip 9.0.1 from /usr/local/lib/python3.6/site-packages (python 3.6)
pip3 should be installed automatically together with Python3.x. The documentation hasn't been updated, so simply replace pip by pip3 in the instructions, when installing Flask for example.
Now, if this doesn't work, you might have to install pip separately.
Update: A more reliable modern way to access the right pip install for the right python install is to use the syntax python -m pip.
Original Answer
pip would install itself into the bin of your python installation location. It also should create a symlink to some more common location like /usr/local/bin/pip
You can either edit your ~/.profile and update your PATH to include /Library/Frameworks/Python.framework/Versions/2.6/bin, or you could create a symlink to it in a place that you know is in your path.
If you do: echo $PATH, you should see the paths currently being searched. If /usr/local/bin is in your PATH, you can do:
ln -s /Library/Frameworks/Python.framework/Versions/2.6/bin/pip /usr/local/bin
I would opt for adding the python bin to your $PATH variable.
I encountered this problem having downloaded python 3.x.x and trying to install awscli - pip: command not found.
Whilst following the instructions for downloading the AWS client, I changed
pip install awscli
to
pip3 install awscli
which ran the correct version.
I've made an alias on my machine to run python3 whilst typing python, which would normally run the system version 2.7. I'm not sure this is a good idea now. I think I'll just type in the commands as they intended them to be.
Check out How to Install Pip article for more information.
As of 2019,
Download get-pip.py provided by https://pip.pypa.io using the following command:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
Run get-pip.py using the following command:
sudo python get-pip.py
After you done installing, run this command to check if pip is installed.
pip --version
Remove get-pip.py file after installing pip.
rm get-pip.py
Install Python latest version as given here
It has many download links like numpy and scipy
Then go to terminal and enter following command:-
sudo easy_install pip
For Python install packages check this
Requirements for Installing Packages
This section describes the steps to follow before installing other Python packages.
Install pip, setuptools, and wheel If you have Python 2 >=2.7.9 or
Python 3 >=3.4 installed from python.org, you will already have pip
and setuptools, but will need to upgrade to the latest version:
On Linux or OS X:
pip install -U pip setuptools On Windows:
python -m pip install -U pip setuptools If you’re using a Python
install on Linux that’s managed by the system package manager (e.g
“yum”, “apt-get” etc…), and you want to use the system package manager
to install or upgrade pip, then see Installing pip/setuptools/wheel
with Linux Package Managers
Otherwise:
Securely Download get-pip.py 1
Run python get-pip.py. 2 This will install or upgrade pip.
Additionally, it will install setuptools and wheel if they’re not
installed already.
I spent ages going through all the answers on this page but found the one that worked for me in the comments of the OP question by s-walsh
The answer is to use pip3:
$ pip3 install <name-of-install>
Installing using apt-get installs a system wide pip, not just a local one for your user. Try this command to get pip running on your system ...
$ sudo apt-get install python-pip python-dev build-essential
Then pip will be installed without any issues and you will be able to use "sudo pip...".
Most of the methods to install PIP are deprecated. Here is the latest (2019) solution. Please download get-pip script
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
Run the script
sudo python get-pip.py
Latest update 2021.
In Ubuntu 20 64bit works perfectly
Installation of python3
sudo apt install python3
Pip Installation
sudo apt install python3-pip
Add following alias in $HOME/.bash_aliases in some cases file may be hidden.
alias pip="/usr/bin/python3 -m pip "
Refresh current terminal session.
. ~/.profile
check pip usage: pip
Install a package: pip install {{package_name}}
extra info
to get Home path
echo $HOME
you will get your home path.
To solve:
Add this line to ~/.bash_profile:
export PATH="/usr/local/bin:$PATH"
In a terminal window, run
source ~/.bash_profile
It might be the root permission. I tried exit root login, and use
sudo su -l root
pip <command>
install Homebrew, open Terminal or your favorite OSX terminal emulator and run
$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
insert the Homebrew directory at the top of your PATH environment variable. You can do this by adding the following line at the bottom of your ~/.profile file
export PATH=/usr/local/bin:/usr/local/sbin:$PATH
Now, we can install Python 2.7:
$ brew install python
Get pip repository:
$ git clone https://github.com/pypa/pip
install pip:
$sudo easy_install pip
python install it by default but if not install you can install it manual use following cmd (for linux only )
for python3 :
sudo apt install python3-pip
for python2
sudo apt install python-pip
hope its help.
If you are running Python 3.5, run the following terminal command:
sudo pip3 install -U nltk
Any other pip commands in terminal would be similar:
pip3 install --upgrade pip
sudo pip3 install -U numpy ::
It solved my problem by using
sudo easy_install pip
Solved this by upgrading python 3 brew upgrade python:
Now i can just do:
pip3 install <package>
==> python
Python has been installed as
/usr/local/bin/python3
Unversioned symlinks `python`, `python-config`, `pip` etc. pointing to
`python3`, `python3-config`, `pip3` etc., respectively, have
Based on this stackoverflow answer and some of the answers on this thread, I have created an alias in the rc file:
alias pip="python3 -m pip"
There seem to be many different answers to this question but this seems to be the best-practice approach.
Avoiding sudo:
python <(curl https://bootstrap.pypa.io/get-pip.py) --user
echo 'export "PATH=$HOME/Library/Python/2.7/bin:$PATH"' >> ~/.bash_profile
From:
http://www.pip-command-not-found.com
CentOS 7 users can just use:
yum install python-pip
Also recommend using virtualenv if you're using pip. It can be added in the same way:
yum install python-virtualenv
assuming you have internet see:
https://pip.pypa.io/en/stable/installing/
basically run:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
and
python get-pip.py
Try using this. Instead of zmq, we can use any package instead of zmq.
sudo apt-get install python3-pip
sudo apt-get update
python3 -m pip install zmq
I was was not able to install this zmq package in my docker image because of the same issue i was getting. So tried this as another way to install and it worked fine for me.
To overcome the issue bash: pip: command not found in Mac
Found two versions on Mac 1 is 2.7 and the other is 3.7
when I say sudo easy_install pip, pip got installed under 2.7
when I say sudo easy_install-3.7 pip, pip got installed under 3.7
But, whenever I would require to do pip install , I wanted to install the package under python3.7, so I have set an alias (alias pip=pip3) in .bash_profile.
so now, whenever I do pip install <package_name>, it gets installed under python3.7
(Context: My OS is Amazon linux using AWS. It seems similar to RedHat but it's stripped down a bit, it seems.)
Exit the shell, then open a new shell. The pip command now works.
That's what solved the problem at this location.
You might want to know as well: The pip commands to install software then needed to be written like this example (jupyter for example) to work correctly on my system:
pip install jupyter --user
Specifically, note the lack of sudo, and the presence of --user
Would be real nice if pip docs had said anything about all this, but that would take typing in more characters I guess.
Not sure why this wasnt mentioned before, but the only thing that worked for me (on my NVIDIA Xavier) was:
sudo apt-get install python3-pip
(or sudo apt-get install python-pip for python 2)
apt -y -qq install python3 python3-pip
ln -s /usr/bin/python3 /usr/bin/python
ln -s /usr/bin/pip3 /usr/bin/pip
What I did to overcome this was sudo apt install python-pip.
It turned out my virtual machine did not have pip installed yet. It's conceivable that other people could have this scenario too.
The updated command for installing pip3 is :
sudo apt-get install python3-pip
The problem seems that your python version and the library yoıu want to install is not matching versionally. Ex: If Django is Django3 and your python version is 2.7, you may get this error.
"After installing is running 'python' still ran Python 2.6 and PATH was not updated."
1- Install latest version of Python
2- Change your PATH manually as python38 and compare them.
3- Try to reinstall.
I solved this problem as replacing PATH manually with the latest version of Python.
As for Windows: ;C:\python38\Scripts
I'm trying to install pip3, but I'm not having any luck. Also, I tried sudo install and it did not work. How could I install pip3 on my Mac?
sudo easy_install pip3

UPDATED - Homebrew version after 1.5
According to the official Homebrew page:
On 1st March 2018 the python formula will be upgraded to Python 3.x and a python#2 formula will be added for installing Python 2.7 (although this will be keg-only so neither python nor python2 will be added to the PATH by default without a manual brew link --force). We will maintain python2, python3 and python#3 aliases.
So to install Python 3, run the following command:
brew install python3
Then, the pip or pip3 is installed automatically, and you can install any package by pip install <package>.
The older version of Homebrew
Not only brew install python3 but also brew postinstall python3
So you must run:
brew install python3
brew postinstall python3
Note that you should check the console, as it might get you errors and in that case, the pip3 is not installed.
You could use Homebrew.
Then just run:
brew install python3
I solved the same problem with these commands:
curl -O https://bootstrap.pypa.io/get-pip.py
sudo python3 get-pip.py
For me brew postinstall python3 didn't work. I found this solution on the GitHub Homebrew issues page:
$ brew rm python
$ rm -rf /usr/local/opt/python
$ brew cleanup
$ brew install python3
Python 3 was working successfully, but without pip3. I tried advice from Stack Overflow, Quora and others (numerous installs and uninstalls).
Python 3 was always fine, but without pip3. Finally I downloaded Python3 from:
https://www.python.org/downloads/
By simple mouse clicks and everything (Python 3 + pip3), it is working fine now.
To install or upgrade pip, download get-pip.py from the official site. Then run the following command:
sudo python get-pip.py
and it will install pip for your python version which runs the script.
Similar to Oksana but add python3
$ brew rm python
$ brew rm python3
$ rm -rf /usr/local/opt/python
$ rm -rf /usr/local/opt/python3
$ brew prune
$ brew install python3
$ brew postinstall python3
Seem now work for pip3 under mac os x 10.13.3 Xcode 9.2
I ran the below where <user>:<group> matched the other <user>:<group> for other files in the /usr/local/lib/python3.7/site-packages/ directory:
sudo chown -R <user>:<group> /usr/local/lib/python3.7/site-packages/pip*
brew postinstall python3
I also encountered the same problem but brew install python3 does not work properly to install pip3.
brre will throw the warning The post-install step did not complete successfully.
It has to do with homebrew does not have permission to /usr/local
Create the directory if not exist
sudo mkdir lib
sudo mkdir Frameworks
Give the permissions inside /usr/local to homebrew so it can access them:
sudo chown -R $(whoami) $(brew --prefix)/*
Now ostinstall python3
brew postinstall python3
This will give you a successful installation
After upgrading to macOS v10.15 (Catalina), and upgrading all my vEnv modules, pip3 stopped working (gave error: "TypeError: 'module' object is not callable").
I found question 58386953 which led to here and solution.
Exit from the vEnv (I started a fresh shell)
sudo python3 -m pip uninstall pip (this is necessary, but it did not fix problem, because it removed the base Python pip, but it didn't touch my vEnv pip)
sudo easy_install pip (reinstalling pip in base Python, not in vEnv)
cd to your vEnv/bin and type "source activate" to get into vEnv
rm pip pip3 pip3.6 (it seems to be the only way to get rid of the bogus pip's in vEnv)
Now pip is gone from vEnv, and we can use the one in the base Python (I wasn't able to successfully install pip into vEnv after deleting)
Installing Pip3
Follow this link to download pip3 on your computer
Follow the instructions on the page and then after successfully downloading Pip3, run python3 get-pip.py in your terminal
This will install pip3 into your laptop and then you can check the installation of pip3 by running which pip3 in your terminal.
Now simply do pip3 install <package>
If you're using Python 3, just execute python3 get-pip.py . It is just a simple command.
