Python Environment Setup for MacOS

There are a few ways to go about this, but I prefer

• Homebrew for package management
• pyenv to manage Python versions, and
• pipenv to manage Python environments.

Install Homebrew

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Make sure to follow the last steps to put brew on the path:

(echo; echo 'eval "$(/opt/homebrew/bin/brew shellenv)"') >> $HOME/.zprofile
eval "$(/opt/homebrew/bin/brew shellenv)"

Install pyenv

brew install pyenv xz
pyenv install 3.11.3
pyenv global 3.11.3

Setup shell env for Pyenv. I use zsh:

echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.zshrc
echo 'command -v pyenv >/dev/null || export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.zshrc
echo 'eval "$(pyenv init -)"' >> ~/.zshrc
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.zshrc

Install pipenv

pip install pipenv --user

Install Xcode command line tools

xcode-select --install
