Python@2 Homebrew Tap

This repo is archived and unmaintained. Use at your own risk. This branch is updated to work with MacOS 12 Monterey.

Why does this exist?

The python@2 was removed from homebrew-core in #49796, as Python 2.7.x is now EOL and should no longer be in general usage.

In order to maintain some legacy applications for my work, I have extracted the last iteration of the python@2 formula to this repository. It has since been updated with Python 2.7.18, the last release (ever!) for Python 2.7.

You should not be using this for any new projects. This is a deprecated formula, and exists here only to facilitate running and supporting software that depends on it.

How do I use it?

Note: Because the binary bottles are no longer hosted by Homebrew, the formula will build from source.

Note 2: If you are on an M1 mac, you must install Python 2 inside Rosetta 2 using a brew installation inside Rosetta 2, see intructions below!

Installation on Intel macs

Add the tap to homebrew:

brew tap odignal/python2

Install as usual, if you are on an Intel Mac:

brew install python@2

Installation on M1 macs

If you are on an M1 Mac, use the following command to install (you might need to install brew in Rosetta 2 first):

Install Rosetta 2:

/usr/sbin/softwareupdate --install-rosetta --agree-to-license

Install brew in Rosetta 2 (using /usr/local/homebrew as installation path):

sudo mkdir /usr/local/homebrew
arch -x86_64 curl -L https://github.com/Homebrew/brew/tarball/master | arch -x86_64 sudo tar xz --strip 1 -C /usr/local/homebrew
sudo chown -R $(whoami) /usr/local/homebrew
echo 'alias brew_x86="arch -x86_64 /usr/local/homebrew/bin/brew"' >> $HOME/.zprofile
echo 'alias brew_arm="/opt/homebrew/bin/brew"' >> $HOME/.zprofile
source ~/.zprofile

Your brew installation in Rosetta 2 is now available with brew_x86, and your normal brew installation on arm64 architecture is available with brew_arm or brew.

Install Python 2 with brew inside Rosetta 2:

brew_x86 install python@2

Python 2 is now available via /usr/local/homebrew/bin/python.

Uninstallation on Intel macs

To uninstall:

brew uninstall python@2

To remove this tap:

brew untap odignal/python2

Uninstallation on M1 macs

To uninstall:

brew_x86 uninstall python@2

To remove this tap:

brew_x86 untap odignal/python2
