How to use pip for python 3.9 instead of inbuilt python 3.8 in Ubuntu?

Question

Today I faced a problem regarding pip3 in Ubuntu. Ubuntu comes with python 3.8 but I wanted to use latest versions of python, like 3.9 or maybe 3.10. So I installed it using 'ppa:deadsnakes' repository and also installed pip. But the problem is I want to use pip in python 3.9 instead of version 3.8. So I changed the default python version to 3.9 and everything crashed. So reverted to python 3.8. Whenever I install some package it gets installed using python 3.8. Help me, how can I use python 3.9 pip and install packages in python 3.9 without changing the default version. Any help is appreciated.

--> Thing I want is that when I want to install python package using pip3 install <package_name> it must install in python3.9 and not in python3.8

Answer 1

Hello everyone I fixed my issue. The problem is we cannot override default python version in Ubuntu as so many things depend on it. So I just made an alias as : alias pip3='python3.9 -m pip' and alias for python : alias python3='/usr/bin/python3.9'

If anyone face this issue please do what I specify and you will be good to go. Now all my packages are being installed in python3.9.

Answer 2

Currently all python3 versions are using the same pip version which can be installed by:

sudo apt-get install python3-pip

The easiest way to work with a specific python version is creating a virtualenv and working under it. When working with a virtualenv you can use pip freely without worrying about which python version it belongs.

Answer 3

you can use pip for python3.9 by pip3.9 install <package-name>

Answer 4

You don't need to install pip separately

You should be able to refer to it as such

python3.9 -m pip install
