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?

Thank you for visiting the Q&A section on Magenaut. Please note that all the answers may not help you solve the issue immediately. So please treat them as advisements. If you found the post helpful (or not), leave a comment & I’ll get back to you as soon as possible.
Method 1
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: runsudo aptitude install python3-setuptools, this will give you the commandeasy_install3. - Install pip using Python 3’s setuptools: run
sudo easy_install3 pip, this will give you the commandpip-3.2like 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!
Method 2
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
Method 3
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.
Method 4
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
Method 5
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
Method 6
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.
Method 7
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
setuptoolsfor Python3 in case you haven’t.apt-get install python3-setuptools
or
aptitude install python3-setuptools
-
With Python 2.4+ you can invoke
easy_installwith specific Python version by usingpython -m easy_install. Sopipfor Python 3 could be installed by:python3 -m easy_install pip
-
That’s it, you got
pipfor Python 3. Now just invokepipwith 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]
Method 8
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
References:
This is a duplicate of question #2812520
Method 9
If your system has python2 as default, use below command to install packages to python3
$ python3 -m pip install <package-name>
Method 10
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
Method 11
You can alternatively just run pip3 install packagename instead of pip,
Method 12
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.
Method 13
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.
Method 14
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 Downloading/unpacking pexpect Downloading pexpect-3.2.tar.gz (131kB): 131kB downloaded Running setup.py (path:/tmp/pip_build_root/pexpect/setup.py) egg_info for package pexpect Installing collected packages: pexpect Running setup.py install for pexpect Successfully installed 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 sklearnto check it.
Method 16
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
Method 17
You Can Simply type in terminal/console .
Commands
sudo apt update sudo apt upgrade sudo apt install python3-pip3 pip3 install package-name
Method 18
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.
