Installing and Managing Multiple Versions of Python - macOS Mojave, Catalina, Big Sur

In this video, I demonstrate how to install, manage, and easily switch between multiple versions of Python 3 with Homebrew using pyenv on macOS Mojave or older, Catalina, or Big Sur.

My demonstration consists of installing 3 versions of Python 3 as well as the last release of Python 2 which is version 2.7.18.

Please note that, as I mention in the video, it is not really recommended to install older versions of Python 3, but in rare circumstances where you need to use a Python package or library and it is not compatible with the latest release, then you can use pyenv to install and manage multiple versions of Python.

You can find pyenv’s documentation on Github here: https://github.com/pyenv/pyenv

In order to be able to use pyenv, you need to have Homebrew installed. If you don’t, I show exactly how to do that in the following videos:
