Overview
This page document how to deal with multiple Python versions on the same system. pyenv is a tool that deals with that.
Python Version Management with Brew
brew install different Python major and minor versions in Cellar using the following naming scheme:
Cellar ├─ ... ├─ python@3.8 ├─ python@3.9 ├─ python@3.10 ├─ python@3.11 ├─ python@3.12 ├─ ...
The default Cellar location is /usr/local/Cellar but may differ depending on the brew instance. See:
Install a Specific Version
brew install python@3.12
If multiple versions are installed this way, only one is symlinked in /usr/local/bin/python and /usr/local/bin/python3 (which one?, looks like the newest one)
To use a specific version other than the one symlinked, update the PATH:
export PATH="/usr/local/opt/python@3.7/bin:${PATH}"
Update a Specific Version to a Newer Patch Level
brew upgrade python@3.12
Get More Info about a Specific Python Version
brew info python@3.9
pip relationship to Python Version
pip installs the packages in a directory
/opt/brew/lib/python3.9/site-packages ?
