Step 4: Set up your environment Step 1: Install Homebrewīefore you can install Python using Homebrew, you need to install Homebrew itself.

Follow below given a step-by-step guide to getting started! Installing Python on your Mac using Homebrew, a package manager that simplifies the process. In this tutorial, we will guide you through the steps required to install Python using Homebrew on your Mac. Homebrew is a package manager for macOS that simplifies the process of installing and updating software. Executable Python scripts will be in $(brew -prefix)/bin.If you are a Mac user, one of the easiest ways to install Python on your system is by using Homebrew. Brewed Python modulesįor brewed Python, modules installed with pip or python3 setup.py install will be installed to the $(brew -prefix)/lib/pythonX.Y/site-packages directory (explained above). Follow the pip documentation to install it for your system Python if you would like it. 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.
