This article will tell you how to install both Python2 (pip2) and Python3 (pip3) on Ubuntu.
1. Install Python2 (pip2) On Ubuntu Steps.
- Ubuntu 20.04 repositories do not contain Python2, so we should install Python 2 in Ubuntu first.
- Run the command sudo add-apt-repository universe to set up the universe repository.
$ sudo add-apt-repository universe 'universe' distribution component is already enabled for all sources.
- Run the command sudo apt update to update the apt packages.
$ sudo apt update Hit:1 http://cn.archive.ubuntu.com/ubuntu focal InRelease ...... Fetched 1,111 kB in 6s (184 kB/s) Reading package lists... Done Building dependency tree Reading state information... Done 203 packages can be upgraded. Run 'apt list --upgradable' to see them.
- Run the command sudo apt install python2 to install python2 on Ubuntu.
$ sudo apt install python2 Reading package lists... Done Building dependency trpythonee Reading state information... Done The following additional packages will be installed: libpython2-stdlib libpython2.7-minimal libpython2.7-stdlib python2-minimal python2.7 python2.7-minimal Suggested packages: python2-doc python-tk python2.7-doc binfmt-support The following NEW packages will be installed: libpython2-stdlib libpython2.7-minimal libpython2.7-stdlib python2 python2-minimal python2.7 python2.7-minimal 0 upgraded, 7 newly installed, 0 to remove and 168 not upgraded.

- After that, you can run the command python2 –version to check whether python2 has been installed successfully or not.
$ python2 --version Python 2.7.18
- You can read the article How To Install The Latest PIP Version And Ipykernel For Python 2.7 to learn how to install pip2 for Python 2.7.
- If you want to invoke the Python2 installed pip command, you can run the command python2 -m pip, this command will run the pip command as a python2 module.
- For example, run the command python2 -m pip list will list all the installed python2 packages, the command python2 -m pip -h will show the pip help content.
- We can add the pip executable file path to the system environment PATH variable’s value and then you can call it directly.
- First, run the command python2 -m pip –version to get the Python2 pip installed location.
$ python2 -m pip --version pip 20.3.4 from /home/jerry/.local/lib/python2.7/site-packages/pip (python 2.7)
- Open a terminal in Ubuntu, run the command cd ~ to go to the user home directory.
- Run the command $ sudo gedit .profile to open the text editor to edit the .profile file.
- Add the text line PATH=”$HOME/.local/lib/python2.7/site-packages/pip:$PATH” at the end of the .profile file.
- Click the Save button to save the changes.
- Run the command . ./.profile to activate the changes.
- Run the command env to print out all the system environment variables values including the PATH variable.
$ env ...... PATH=/home/jerry/.local/lib/python2.7/site-packages/pip:/home/jerry/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin ......
- Now you can run the pip command directly in the terminal.
$ pip --version pip 20.3.4 from /home/jerry/.local/lib/python2.7/site-packages/pip (python 2.7)
2. Install Python3 (pip3) On Ubuntu Steps.
- Run the command sudo apt update to update the apt packages.
- Run the command sudo apt install python3-pip to install Python 3 and pip.
$ sudo apt install python3-pip Reading package lists... Done Building dependency tree Reading state information... Done The following additional packages will be installed: libexpat1-dev libpython3-dev libpython3.8 libpython3.8-dev libpython3.8-minimal libpython3.8-stdlib python-pip-whl python3-dev python3-distutils python3-setuptools python3-wheel python3.8 python3.8-dev python3.8-minimal zlib1g-dev Suggested packages: python-setuptools-doc python3.8-venv python3.8-doc binfmt-support The following NEW packages will be installed: libexpat1-dev libpython3-dev libpython3.8-dev python-pip-whl python3-dev python3-distutils python3-pip python3-setuptools python3-wheel python3.8-dev zlib1g-dev The following packages will be upgraded: libpython3.8 libpython3.8-minimal libpython3.8-stdlib python3.8 python3.8-minimal 5 upgraded, 11 newly installed, 0 to remove and 163 not upgraded.

- After that, you can run the command python3 –version and pip3 –version to check the installation result. If you get the below output that means your installation is successful.
$ python3 --version Python 3.8.10 $ pip3 --version pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.8)
3. How To Upgrade PIP Versions.
- Run the below command to upgrade the pip installation for python3.
$ python3 -m pip install --upgrade pip ...... Installing collected packages: pip Successfully installed pip-21.3.1
- After you upgrade the pip successfully and restart the Ubuntu OS, you will find the system has created 3 files related to pip, they are pip, pip2, pip3, you can run the below command to get the 3 pip related files saved directory & version.
$ which pip /home/jerry/.local/bin/pip $ pip --version pip 21.3.1 from /home/jerry/.local/lib/python3.8/site-packages/pip (python 3.8) $ which pip2 /home/jerry/.local/bin/pip2 $ pip2 --version pip 20.3.4 from /home/jerry/.local/lib/python2.7/site-packages/pip (python 2.7) $ which pip3 /home/jerry/.local/bin/pip3 $ pip3 --version pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.8)
