This stopped working and now throws No module named 'urllib3'

[ibehnam]

This used to work until about a month ago when it suddenly stopped working. This is the error I'm getting:

✨ llm keys set openrouter                                                                                                                  18:20:45

Solved by llm install urllib3. Didn't know we could install Python dependencies through llm, but your workaround regarding Homebrew limitations made me think of this solution. pipx wouldn't let me install urllib3, saying that it's not a dependency for any package.

Thanks for the bug report, maybe this is a Python 3.12 thing? I'll add urllib3 as a direct dependency (once I recreate the bug).

[ibehnam]

@simonw Yes, it's Python 3.12. The bug actually was worse than I thought because once it happens, also messes with the other functionality of llm as well. Had to pipx uninstall it a few times as it wouldn't let me set the API keys either.

Actually I had a fix for this already, I just hadn't pushed it yet.
