But when i run command sudo apt-get install python3-pip. It is installed but inot as python3.6. It is installed in python3.5.I have also specified the version in command i.e sudo apt-get install python3.6-pip.But it gives me an error.

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'
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 wanted to deploy my Python app on Amazon Linux AMI 2015.09.1, which has Python2.7 (default) and pip (6.1.1). Then, I upgraded the pip using the command:
sudo pip install -U pip
However, it seemed broken, and showed the message when I tried to install packages:
pkg_resources.DistributionNotFound: pip==6.1.1
I found out that pip remove the previous files located in /usr/bin/, and installed the new one in /usr/local/bin. Thus, I tried to specify the location by using the command:
sudo pip install -U --install-option="--prefix='/usr/bin'" pip
Nevertheless, it still installed the new one in /usr/local/bin. In addition to that, pip could not work well with sudo although it successfully installed. The error message :
sudo: pip2.7: command not found
Is there a way to properly manage pip?
Try:
sudo which pip
This may reveal something like 'no pip in ($PATH)'.
If that is the case, you can then do:
which pip
Which will give you a path like /usr/local/bin/pip.
Copy + paste the path to pip to the sbin folder by running: sudo cp /usr/local/bin/pip /usr/sbin/
This will allow you to run sudo pip without any errors.
Struggled with this for a while. Here's what I've found:
ec2_user finds the pip executable, but has a module import error due to other having no read/execute permissions on the pip folders in the /usr/local/lib/python2.7/site-packages folder. This is actually okay, since in most cases, pip installs fail when not run as root anyway.
sudo cannot find pip.
Entering root with sudo su - allows pip to be run without issue.
The reason sudo pip stops working after the upgrade, is because the executable (or symbolic link) is removed from /usr/bin. However, what remains is a file called pip-27, which contains the following:
#!/usr/bin/python2.7
# EASY-INSTALL-ENTRY-SCRIPT: 'pip==6.1.1','console_scripts','pip2.7'
__requires__ = 'pip==6.1.1'
import sys
from pkg_resources import load_entry_point
if __name__ == '__main__':
sys.exit(
load_entry_point('pip==6.1.1', 'console_scripts', 'pip2.7')()
)
So, that's where our error comes from, as the upgrade clearly doesn't clean this file up. Not entirely clear on where the name translation from pip to pip-2.7 occurs.
As mentioned in another answer, pip now exists in /usr/local/bin after the upgrade, which is no longer in the sudo secure path. You can add this path to the secure_path variable by running sudo visudo. Another alternative, if you'd prefer to not add that path to your secure_path is to make a symbolic link to the new pip executable in /usr/bin.
The problem is partly answered by your question. The Amazon AMI doesn't consider /usr/local/bin to be part of the root account's PATH. You can fix this by updating the root account's ~/.bashrc to include it.
Something like this...
export PATH=$PATH:/usr/local/bin
After struggling with this for hours and reading comments
which pip gave /usr/bin/pip , but the actual pip was located at /usr/local/bin/pip due to pip upgrade and clean up was not complete
So removing the pip in /usr/bin/
sudo rm /usr/bin/pip
and also adding the new pip to your export path
vim ~/.bash_profile
PATH=$PATH:$HOME/bin:/usr/local/bin
exit terminal, and login back
which pip should give /usr/local/bin/pip
pip install --upgrade pip
This works for me
sudo /usr/local/bin/pip install --upgrade pip
To add to angelokh
sudo `which pip` install --upgrade pip
I think the best strategy in this case is to manage pip is as part of a virtual environment using virtualenv rather than messing with the system-level version.
If you're OK with that, here's the basic idea:
Install the version of virtualenv packaged with the version of pip you are looking to upgrade to to the system-level pip (e.g. virtualenv==15.1.0 comes with pip==9.0.1):
$ sudo pip install -U virtualenv==15.1.0
You are using pip version 6.1.1, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Collecting virtualenv==15.1.0
Downloading virtualenv-15.1.0-py2.py3-none-any.whl (1.8MB)
100% |████████████████████████████████| 1.8MB 135kB/s
Installing collected packages: virtualenv
Found existing installation: virtualenv 12.0.7
Uninstalling virtualenv-12.0.7:
Successfully uninstalled virtualenv-12.0.7
Successfully installed virtualenv-15.1.0
I used the virtualenv release notes to find out which version of pip corresponds to which version of virtualenv.
Create the virtual environment:
$ virtualenv myenv
New python executable in /home/ec2-user/myenv/bin/python2.7
Also creating executable in /home/ec2-user/myenv/bin/python
Installing setuptools, pip, wheel...done.
Activate the virtual environment and confirm the version and location of the upgraded pip:
$ source myenv/bin/activate
(myenv) $ pip -V
pip 9.0.1 from /home/ec2-user/myenv/local/lib/python2.7/dist-packages (python 2.7)
(myenv) $ which pip
~/myenv/bin/pip
This should allow you to install packages to this virtualenv using the pip version of your choice, without the need for sudo.
I think you've didn't installed the pythonXX-pip package.
I've upgraded mine straight to Python3.4, these commands works for me.
sudo su
yum install python34
yum install python34-pip
I installed python-pip package via yum (using Fedora's updates repo). It does not add the pip script to my PATH though.
$ which pip
/usr/bin/which: no pip in
(/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/bin:/bin:
/usr/bin:/usr/local/sbin:/usr/sbin:/sbin)
It does, however, create pip-python:
$ rpm -ql python-pip
/usr/bin/pip-python
[...snip...]
$ which pip-python
/usr/bin/pip-python
I was considering making pip a symbolic link to pip-python but is there a reason the executable is named pip-python to begin with?
If you install the python-pip package and then run:
pip-python install -U pip
pip will fix itself.
It is probably to avoid a conflict with another package that has an executable called pip. As long as you don't install that package, you should be safe.
Another annoying example of this is the chromium browser, which my distro's executable is chromium-browser to avoid a conflict with some game I had never heard of until I did an: apt-get install chromium.
This used to be the case on Fedora, due to the conflict noted with the perl-pip package. With the gracious consent of the perl-pip packager, this has been updated in recent versions, so installing pip-python on Fedora 17 or later now installs /usr/bin/pip
