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>

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
Running debian jessie
I installed Ansible using the following procedure:
apt-get update
sudo apt-get install python-yaml python-pip python-jinja2 python-paramiko pip
git clone https://github.com/ansible/ansible.git
cd ansible
git submodule update --init --recursive
sudo make install
Is there a way to cleanly uninstall Ansible that does not involve sifting through my directory tree and deleting?
The aim is to reinstall Ansible version 1.9 instead of the latest 2.1.0
Your best bet is to install checkinstall, run the install again under checkinstalls control, and then use dpkg to remove things.
https://wiki.debian.org/CheckInstall
There is a directory list in the source code repo telling you which directories ( and files ) are created. This is used to build the .deb package, but you can easily use it the other way around:
packaging/debian/ansible.dirs
if you have installed on redhat centos based systems
you can do below to uninstall ansible cleanly and similar command for ubuntu debian based systems
rpm -qa | grep ansible | xargs rpm -e
rpm -qa | grep -i epel | xargs rpm -e
else yum remove ansible
As I see you cloned ansible from git. Try to remove ansible folder, but first, go to cloned folder and write
make uninstall
then
cd ..
rm -r ansible_folder
and dependent folders, files for example '/etc/ansible' folder.
I had built ansible 2.1.1 from source then wanted to downgrade to 2.1.0 using yum. The trick i learned was to go to /lib/python2.7/site-packages and deleting the ansible-2.1.1.0-py2.7.egg-info directory. In my case, using yum properly added files to /etc/ansible and /usr/bin, but as long as the old (newer version number) egg was there, then ansible --version continued to show the newer version number.
After removing ansible using dnf remove ansible uninstall python and reinstall ansible it will show the newer version.
I have a pip requirements file that changes during development.
Can pip be made to uninstall packages that do not appear in the requirements file as well as installing those that do appear? Is there a standard method?
This would allow the pip requirements file to be the canonical list of packages - an 'if and only if' approach.
Update: I suggested it as a new feature at https://github.com/pypa/pip/issues/716
This should uninstall anything not in requirements.txt:
pip freeze | grep -v -f requirements.txt - | grep -v '^#' | xargs pip uninstall -y
Although this won't work quite right with packages installed with -e, i.e. from a git repository or similar. To skip those, just filter out packages starting with the -e flag:
pip freeze | grep -v -f requirements.txt - | grep -v '^#' | grep -v '^-e ' | xargs pip uninstall -y
Then, obviously:
pip install -r requirements.txt
Update for 2016:
You probably don't really want to actually use the above approach, though. Check out pip-tools and pip-sync which accomplish what you are probably looking to do in a much more robust way.
https://github.com/nvie/pip-tools
Update for May, 2016:
You can now also use pip uninstall -r requirements.txt, however this accomplishes basically the opposite - it uninstalls everything in requirements.txt
Update for May, 2019:
Check out pipenv or Poetry. A lot has happened in the world of package management that makes this sort of question a bit obsolete. I'm actually still quite happily using pip-tools, though.
You can now pass the -r requirements.txt argument to pip uninstall.
pip uninstall -r requirements.txt -y
At least as of pip 8.1.2, pip help uninstall shows:
...
Uninstall Options:
-r, --requirement <file> Uninstall all the packages listed in the given requirements file. This option can be
used multiple times.
...
It's not a feature of pip, no. If you really want such a thing, you could write a script to compare the output of pip freeze with your requirements.txt, but it would likely be more hassle than it's worth.
Using virtualenv, it is easier and more reliable to just create a clean environment and (re)install from requirements.txt, like:
deactivate
rm -rf venv/
virtualenv venv/
source venv/bin/activate
pip install -r requirements.txt
The short answer is no, you can't do that with pip.
Here's a simple solution that works:
pip uninstall $(pip freeze) -y
This is an old question (but a good one), and things have changed substantially since it was asked.
There's an offhand reference to pip-sync in another answer, but deserves its own answer, because it solves precisely the OP's problem.
pip-sync takes a requirements.txt file as input, and "trues up" your current Python environment so that it matches exactly what's in that requirements.txt. This includes removing any packages that are present in your env but absent from requirements.txt.
Example: Suppose we want our env to contain (only) 3 libraries: libA, libB, and libC, like so:
> cat requirements.txt
libA==1.0
libB==1.1
libC==1.2
But our env currently contains libC and libD:
> pip freeze
libC==1.2
libD==1.3
Running pip-sync will result in this, which was our desired final state:
> pip-sync requirements.txt
> pip freeze
libA==1.0
libB==1.1
libC==1.2
Stephen's proposal is a nice idea, but unfortunately it doesn't work
if you include only direct requirements in your file, which sounds
cleaner to me.
All dependencies will be uninstalled,
including even distribute, breaking down pip itself.
Maintaining a clean requirements file while version tracking a virtual environment
Here is how I try to version-track my virtual environment.
I try to maintain a minimal requirements.txt, including only
the direct requirements, and not even mentioning version constraints where
I'm not sure.
But besides, I keep, and include in version tracking (say git),
the actual status of my virtualenv in a venv.pip file.
Here is a sample workflow:
setup virtualenv workspace, with version tracking:
mkdir /tmp/pip_uninstalling
cd /tmp/pip_uninstalling
virtualenv venv
. venv/bin/activate
initialize version tracking system:
git init
echo venv > .gitignore
pip freeze > venv.pip
git add .gitignore venv.pip
git commit -m "Python project with venv"
install a package with dependencies, include it in requirements file:
echo flask > requirements.txt
pip install -r requirements.txt
pip freeze > venv.pip
Now start building your app, then commit and start a new branch:
vim myapp.py
git commit -am "Simple flask application"
git checkout -b "experiments"
install an extra package:
echo flask-script >> requirements.txt
pip install -r requirements.txt
pip freeze > venv.pip
... play with it, and then come back to earlier version
vim manage.py
git commit -am "Playing with flask-script"
git checkout master
Now uninstall extraneous packages:
pip freeze | grep -v -f venv.pip | xargs pip uninstall -y
I suppose the process can be automated with git hooks, but let's not go off topic.
Of course, it makes sense then to use some package caching system
or local repository like pip2pi
you can create a new file with all installed packages
pip freeze > uninstall.txt
and then uninstall all of those
pip uninstall -r uninstall.txt -y
and then finally re-install the packages you had in your original requirements.txt file
pip install -r requirements.txt
Piggybacking off #stephen-j-fuhry here is a powershell equivalent I use:
pip freeze | ? { $_ -notmatch ((gc req.txt) -join "|") }
While this doesn't directly answer the question, a better alternative to requirements.txt now is using a Pipfile. This functions similarly to a Ruby Gemfile. Currently, you need to make use of the pipenv tool but hopefully this will eventually be incorporated into pip. This provides the pipenv clean command which does what you want.
(Note that you can import an existing requirements.txt with pipenv install -r requirements.txt. After this you should have a Pipfile and the requirements.txt can be removed.)
It is possible now using:
pip uninstall -r requirements.txt
I have both python2.7 and python3.2 installed in Ubuntu 12.04.
The symbolic link python links to python2.7.
When I type:
sudo pip install package-name
It will default install python2 version of package-name.
Some package supports both python2 and python3.
How to install python3 version of package-name via pip?
Ubuntu 12.10+ and Fedora 13+ have a package called python3-pip which will install pip-3.2 (or pip-3.3, pip-3.4 or pip3 for newer versions) without needing this jumping through hoops.
I came across this and fixed this without needing the likes of wget or virtualenvs (assuming Ubuntu 12.04):
Install package python3-setuptools: run sudo aptitude install python3-setuptools, this will give you the command easy_install3.
Install pip using Python 3's setuptools: run sudo easy_install3 pip, this will give you the command pip-3.2 like kev's solution.
Install your PyPI packages: run sudo pip-3.2 install <package> (installing python packages into your base system requires root, of course).
…
Profit!
You may want to build a virtualenv of python3, then install packages of python3 after activating the virtualenv. So your system won't be messed up :)
This could be something like:
virtualenv -p /usr/bin/python3 py3env
source py3env/bin/activate
pip install package-name
Short Answer
sudo apt-get install python3-pip
sudo pip3 install MODULE_NAME
Source: Shashank Bharadwaj's comment
Long Answer
The short answer applies only on newer systems. On some versions of Ubuntu the command is pip-3.2:
sudo pip-3.2 install MODULE_NAME
If it doesn't work, this method should work for any Linux distro and supported version:
sudo apt-get install curl
curl https://bootstrap.pypa.io/get-pip.py | sudo python3
sudo pip3 install MODULE_NAME
If you don't have curl, use wget. If you don't have sudo, switch to root. If pip3 symlink does not exists, check for something like pip-3.X
Much python packages require also the dev package, so install it too:
sudo apt-get install python3-dev
Sources:
python installing packages with pip
Pip latest install
Check also Tobu's answer if you want an even more upgraded version of Python.
I want to add that using a virtual environment is usually the preferred way to develop a python application, so #felixyan answer is probably the best in an ideal world. But if you really want to install that package globally, or if need to test / use it frequently without activating a virtual environment, I suppose installing it as a global package is the way to go.
Well, on ubuntu 13.10/14.04, things are a little different.
Install
$ sudo apt-get install python3-pip
Install packages
$ sudo pip3 install packagename
NOT pip-3.3 install
The easiest way to install latest pip2/pip3 and corresponding packages:
curl https://bootstrap.pypa.io/get-pip.py | python2
pip2 install package-name
curl https://bootstrap.pypa.io/get-pip.py | python3
pip3 install package-name
Note: please run these commands as root
I had the same problem while trying to install pylab, and I have found this link
So what I have done to install pylab within Python 3 is:
python3 -m pip install SomePackage
It has worked properly, and as you can see in the link you can do this for every Python version you have, so I guess this solves your problem.
Old question, but none of the answers satisfies me. One of my systems is running Ubuntu 12.04 LTS and for some reason there's no package python3-pip or python-pip for Python 3. So here is what I've done (all commands were executed as root):
Install setuptools for Python3 in case you haven't.
apt-get install python3-setuptools
or
aptitude install python3-setuptools
With Python 2.4+ you can invoke easy_install with specific Python version by using python -m easy_install. So pip for Python 3 could be installed by:
python3 -m easy_install pip
That's it, you got pip for Python 3. Now just invoke pip with the specific version of Python to install package for Python 3. For example, with Python 3.2 installed on my system, I used:
pip-3.2 install [package]
If you have pip installed in both pythons, and both are in your path, just use:
$ pip-2.7 install PACKAGENAME
$ pip-3.2 install PACKAGENAME

This is a duplicate of question #2812520
If your system has python2 as default, use below command to install packages to python3
$ python3 -m pip install <package-name>
Easy enough:
sudo aptitude install python3-pip
pip-3.2 install --user pkg
If you want Python 3.3, which isn't the default as of Ubuntu 12.10:
sudo aptitude install python3-pip python3.3
python3.3 -m pip.runner install --user pkg
You can alternatively just run pip3 install packagename instead of pip,
Firstly, you need to install pip for the Python 3 installation that you want. Then you run that pip to install packages for that Python version.
Since you have both pip and python 3 in /usr/bin, I assume they are both installed with a package manager of some sort. That package manager should also have a Python 3 pip. That's the one you should install.
Felix' recommendation of virtualenv is a good one. If you are only testing, or you are doing development, then you shouldn't install the package in the system python. Using virtualenv, or even building your own Pythons for development, is better in those cases.
But if you actually do want to install this package in the system python, installing pip for Python 3 is the way to go.
Although the question relates to Ubuntu, let me contribute by saying that I'm on Mac and my python command defaults to Python 2.7.5. I have Python 3 as well, accessible via python3, so knowing the pip package origin, I just downloaded it and issued sudo python3 setup.py install against it and, surely enough, only Python 3 has now this module inside its site packages. Hope this helps a wandering Mac-stranger.
Execute the pip binary directly.
First locate the version of PIP you want.
jon-mint python3.3 # whereis ip
ip: /bin/ip /sbin/ip /usr/share/man/man8/ip.8.gz /usr/share/man/man7/ip.7.gz
Then execute.
jon-mint python3.3 # pip3.3 install pexpect

Cleaning up...
You should install ALL dependencies:
sudo apt-get install build-essential python3-dev python3-setuptools python3-numpy python3-scipy libatlas-dev libatlas3gf-base
Install pip3(if you have installed, please look step 3):
sudo apt-get install python3-pip
Iinstall scikit-learn by pip3
pip3 install -U scikit-learn
Open your terminal and entry python3 environment, type import sklearn to check it.
To install pip for python3 use should use pip3 instead of pip.
To install python in ubuntu 18.08 bionic
before installing a version of python, activate virtual environment so that it won't have any problem in a future versions of python.
virtualenv -p /usr/bin/python3 py3env
source py3env/bin/activate
then install the actual python version you want.
>> sudo apt-get install python3.7
To install the required pip package in ubuntu
>> sudo apt-get install python3-pip
You Can Simply type in terminal/console .
Commands
sudo apt update
sudo apt upgrade
sudo apt install python3-pip3
pip3 install package-name
Another way to install python3 is using wget. Below are the steps for installation.
wget http://www.python.org/ftp/python/3.3.5/Python-3.3.5.tar.xz
tar xJf ./Python-3.3.5.tar.xz
cd ./Python-3.3.5
./configure --prefix=/opt/python3.3
make && sudo make install
Also,one can create an alias for the same using
echo 'alias py="/opt/python3.3/bin/python3.3"' >> ~/.bashrc
Now open a new terminal and type py and press Enter.
