⚒️ Python Local Setup Cheatsheet

Python is a common runtime for many automation tasks, and local setup remains relevant even though you can containerize your scripts or applications — convenience is still king.

Python version manager

• pyenv/pyenv: Simple Python version management
• pyenv/pyenv-virtualenv: a pyenv plugin to manage virtualenv (a.k.a. python-virtualenv)

Commands

1. brew install pyenv (Installing via Homebrew is still the easiest option.)

2. You may need the following commands to enable pyenv to auto-load in your default shell environment.

   echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.zshrc
   echo '[[ -d $PYENV_ROOT/bin ]] && export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.zshrc
   echo 'eval "$(pyenv init - zsh)"' >> ~/.zshrc
   

3. pyenv install -l (List all available Python versions)

4. pyenv install (Install the Python version according to local .python-version file)

5. pyenv local xxx (Lock a Python version locally)

6. brew install pyenv-virtualenv (Install virtualenv to provide additional package isolation for each project.)

7. You may need the following commands to enable pyenv-virtualenv to auto-load in your default shell environment.

   echo 'eval "$(pyenv virtualenv-init -)"' >> ~/.zshrc
