Python Development on macOS Notes: pyenv and pyenv-virtualenvwrapper (via) Jeff Triplett shares the recipe he uses for working with pyenv (initially installed via Homebrew) on macOS.
I really need to start habitually using this. The benefit of pyenv over Homebrew’s default Python is that pyenv managed Python versions are forever—your projects won’t suddenly stop working in the future when Homebrew changes its default Python version.
