uv python list doesn't find pypy

[hynek]

I find uv python list an amazing tool to debug Python Environment xkcd situations, even tho I don't use uv for downloads. But find my PyPy installation (I could've sworn it used to but I might be wrong).

Here's le output to demonstrate:

❯ type pypy3.10
pypy3.10 is /opt/homebrew/bin/pypy3.10

~
❯ uv --version
uv 0.4.9 (77d278f68 2024-09-10)

I can use it to create venvs, though:

❯ uv venv --python pypy3.10 foo
Using Python 3.10.14 interpreter at: /opt/homebrew/bin/pypy3.10
Creating virtualenv at: foo
Activate with: source foo/bin/activate.fish

That's surprising. I'll look into this.

Btw if you don't want to see the downloads you can use uv python list --only-installed or set your python-preference to `only-system

Ohhh loving it! I didn’t mind the download available but this is really cool.

I think this is because, generally, we don't look for pypy executables unless you request PyPy so we exclude them here. I'll need to do some refactors to fix this.

That’s kinda funny in combination with #7118 — sorry for running into all edge cases. 🙈

[zanieb]

I appreciate it :)
