Homebrew Python

Homebrew-formulae to install Python 2.x and 3.x libraries, which are not yet well supported by pip install due to compiler and dependency issues.

Why not pip?

  • Numpy
    • optionally link against the openBLAS (--with-openblas)
  • SciPy
    • optionally link against the openBLAS (--with-openblas)
  • Matplotlib
    • Support all optional deps, installable by brew (e.g. PyGTK, cairo, ghostscript, tk, freetype and libpng)
  • matplotlib-basemap (library for plotting 2D data on maps)
    • Deps installed by brew (numpy, matplotlib, pillow, geos)
  • PIL (brew install pillow)
    • The Python Image Library in the newer distribution named "pillow"
    • Support for zlib/PNG
    • Freetype2 support
    • Little-CMS (for color management)
  • PyGame (Game development and provides bindings to SDL)
  • ReText (Markdown Editor)
    • Supports enchant. (You first need to brew install enchant)
    • Some deps have to be installed via pip (it will tell you so)
  • Open an issue if your favorite is missing

How do I install these formulae?

brew install homebrew/python/<formula>

Or brew tap homebrew/python and then brew install <formula>.

Or install via URL (which will not receive updates):

brew install<formula>.rb


Check main Homebrew Troubleshooting guide and then open an issue in this tap.


Homebrew Python modules install to whichever Python is first in the PATH. Our formulas are tested against Homebrew Python as well as the Python that came with your Mac.

We support Python 2.x and 3.x. For simultaneous support, use the brew install <formula> --with-python3. And if you don't need Python 2.x support at all:

brew install <formula> --with-python3 --without-python

How to add a new formulae here

  • Fork this repository on GitHub.
  • Clone to your Mac.
  • Read Homebrew and Python and look at the other formulae here.
  • In your locally cloned homebrew-python repo, create a new branch: git checkout --branch my_new_formula
  • Write/edit your formula (ruby file). Check the Homebrew's documentation for details.
  • Test it locally! brew install ./my-new-formula.rb. Does it install? Note, how ./<formula>.rb will target the local file.
  • git push --set-upstream origin my-new-formula to get it into your GitHub fork as a new branch.
  • If you have to change something, add a commit and git push.
  • On GitHub, select your new branch and then click the "Pull Request" button.
