We’re going to use Python 3, so start by installing Python 3 on your system. We’ll also need pip3. On Debian, I install them both by entering the command, sudo apt-get install python3 python3-pip.

If you’ve upgraded an existing Python interpreter with a minor point upgrade—e.g., from Python 3.11.1 to Python 3.11.3—you can upgrade any corresponding virtual environments easily enough.

Now, If you are using an older version of Python on Windows, you may need to install PIP manually. Pip is automatically installed with Python 2.7.9+ and Python 3.4+.
