Note: macOS’s system Python does not provide pip. These should be installed via pip install. pyside, wxwidgets, pyqt, pygobject3, opencv, vtk and boost-python). If you decide to switch to the brewed Python, then reinstall all formulae with Python bindings (e.g. Warning! Python may crash (see Common Issues) when you import from a brewed Python if you ran brew install against the system Python. Additionally, Homebrew has a strict policy never to write stuff outside of the brew -prefix, so we don’t spam your system. The reasoning for this location is to preserve your modules between (minor) upgrades or re-installations of Python. Homebrew’s site-packages directory is first created (1) once any Homebrew formulae with Python bindings are installed, or (2) upon brew install python. ~/Library/Python/3.y/lib/python/site-packages.So, for Python 3.y.z, you’ll find it at /usr/local/lib/python3.y/site-packages. $(brew -prefix )/lib/pythonX.Y/site-packages Unversioned symlinks for python, python-config, pip etc. pip3 points to Homebrew’s Python 3.y’s pip (if installed).python3 points to Homebrew’s Python 3.y (if installed).The executables are organised as follows: Manager such as pyenv if you require stability of minor or patch versions for virtual environments. ![]() Homebrew provides formulae for maintained releases of Python 3.y ( Python may be upgraded to a newer version at any time. Important: If you choose to use a Python which isn’t either of these two (system Python or brewed Python), the Homebrew team cannot support any breakage that may occur. ![]() A formula was provided until the end of 2019, at which point it was removed due to the Python 2 deprecation. Homebrew provides formulae to brew Python 3.y. Homebrew should work with any CPython and defaults to the macOS system Python. ![]() See Python for Formula Authors for advice on writing formulae to install packages written in Python. This page describes how Python is handled in Homebrew for users.
