This process uses pyenv to manage Python installation and versions. pyenv is a Python version manager that can manage and install different versions of Python.

Install pyenv with homebrew

brew install pyenv

Add the following lines to update your ~/.zshrc / ~/.zprofile files, instructing them to use pyenv to manage Python:

export PYENV_ROOT="$HOME/.pyenv"
[[ -d $PYENV_ROOT/bin ]] && export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init -)"

Install additional dependencies required to build Python

brew install openssl readline sqlite3 xz zlib tcl-tk

pyenv install 3.12
pyenv install 3.11
pyenv install 3.10
pyenv install 3.9
pyenv install 3.8

pipx#

Install pipx

pipx is a tool to help you install and run end-user applications written in Python. It's roughly similar to macOS's brew, JavaScript's npx, and Linux's apt.

It's closely related to pip. In fact, it uses pip, but is focused on installing and managing Python packages that can be run from the command line directly as applications.

brew install pipx
pipx ensurepath

Add the following lines to update your ~/.zshrc file, instructing it to use pyenv's default Python version to bootstrap pipx applications:

export PIPX_DEFAULT_PYTHON=$(pyenv which python)
