How to install Python 3.3 (not 3.4) on OS X with Homebrew?
django, homebrew, macos, python, python-3.x
Solution
Here are some elements that you can piece together from the homebrew FAQ.
Can I edit formulae myself? - yes.
brew edit python3
look for the `url` and change it to the ftp link to the `3.3` (`3.3.6`) archive.
download the archive locally and compute the checksum with `shasum`.
save the file as `python33.rb` and install with `brew install --debug python33.rb`.
Passing the `--debug` flag will help you in case some steps are not working properly (e.g. in the latest formula, removing the `2to3` binary was a problem), you may just try to revert this change as python3.3 does not have `ensurepip` bootstrap module.
You can find the formula I used here: python 3.3.5
Problem
If you install python3 through Homebrew it installs the latest version by default, which I did. But I want 3.3 instead of 3.4. How can I replace it with 3.3 specifically using Homebrew? I want to try Django with Python 3 but I'm just learning Django so I want to use the latest stable version, currently 1.6, which is compatible with up to Python 3.3. I want to use it with Python 3, so it has to be 3.3. Django 1.7 is Py3.4 compatible but I don't want to mess with that 'til it's stable... on OS X 10.8.5
