How to reinstall python@2 from Homebrew?

by

You can use pyenv to install python with:

brew install pyenv
pyenv install 2.7.18

Optionally set it to your global default:

pyenv global 2.7.18

Nice article on why using pyenv is better than using brew to manage your python installation.

To make python binary available globally, add shims to PATH:

PATH=$(pyenv root)/shims:$PATH
