How to downgrade python version back to 3.9

[macdrorepo]

Hello,

How I can downgrade python version on my macos from 3.10 to 3.9? 3.10 breaks some stuff internal to my company and of course I forget to suppress auto update. Brew list gets me:

python@3.10 python@3.9

Was trying to un-link 3.10 and link back 3.9 without success. Uninstall 3.10 can potentially break other packages

Error: Refusing to uninstall /usr/local/Cellar/python@3.10/3.10.8 because it is required by ansible, ansible-lint, jsonschema, ldns, openssh, pipx, pre-commit and yamllint, which are currently installed.

So how can I go back to 3.9?

You can't downgrade packages, especially ones that other software depends on. The best way is just to put python 3.9 first in your path (or have your corporate software use #!/usr/bin/env python@3.9 as shebang). To put python 3.9 first in your path you can do export PATH="$(brew --prefix python@3.10)/bin:$PATH".

So putting this to export to zshrc should solve the issues i guess?

I'd start by running it once, but generally yes

Thx didn't do a trick. So I've removed homebrew and want to get back to "original" python in MacOS. Now I'm getting:
bad interpreter: /usr/local/opt/python@3.10/bin/python3.10: no such file or directory of course as I've removed it. Do you know how to correct that maybe?

[SMillerDev]

Don't call scripts that depend on the Homebrew version of python.

[macdrorepo]

But I've removed whole hombrew seems some setup persists...

[macdrorepo]

So I did get rid of that by installing python from installer (3.9) and modify the PATH accordingly.
Solved myslef.

hey, could you specify what commands did you use?

I believe this works:

brew uninstall --ignore-dependencies python@3.10
brew install python@3.9

just be mindful of dependencies that might break

My suggestion, use pyenv it was created for that

@fedexin40 pyenv does not work for me. It stucks at xcode part
