Set up Homebrew-installed Python to be used by Pyenv

how-to-setup-homebrew-python-with-pyenv.md

Did this while installing Azure CLI on my Mac.

At install time this had a dependency on Python 3.10 that I tried to resolve using the version 3.10.11 that was installed via Pyenv. Could not get this to work so uninstalled 3.10.11 via Pyenv, did a pyenv rehash, and then installed 3.10.11 directly via Homebrew: brew install [email protected]

I then set up Pyenv to be able to use this new version via a variation of the instructions found here. This required some changes though because the symlinks weren't right in the example given because I wanted the specific version of Python installed via Homebrew. If I wanted python3 in my PATH without needing Pyenv the install would have been brew install python3 which likely would have meant the symlink setup below would have been different.

This is what I had to do.

1. cd ~/.pyenv/versions
2. ln -sfv "$(brew --prefix [email protected])" 3.10.11
3. pyenv rehash
4. cd /opt/homebrew/Cellar/[email protected]/3.10.11
5. ln -sfv ../Frameworks/Python.framework/Versions/3.10/bin/idle3.10 idle3
6. ln -sfv ../Frameworks/Python.framework/Versions/3.10/bin/idle3.10 idle
7. ln -sfv pip3.10 pip
8. ln -sfv pip3.10 pip3
9. ln -sfv ../Frameworks/Python.framework/Versions/3.10/bin/python3.10 python3
10. ln -sfv ../Frameworks/Python.framework/Versions/3.10/bin/python3.10 python
11. ln -sfv wheel3.10 wheel
12. ln -sfv wheel3.10 wheel3
13. ln -sfv ../Frameworks/Python.framework/Versions/3.10/bin/pydoc3.10 pydoc
14. ln -sfv ../Frameworks/Python.framework/Versions/3.10/bin/pydoc3.10 pydoc3
15. pyenv rehash
