`uv python list` breaks when used from within WSL when Python installed via `pyenv-win`

[brysonwu]

Summary

Probably a very niche scenario but thought I should let folks know this issue exists.

Reproduction

• Install uv in WSL and pyenv-win in Windows.
• uv python list will work at this point.
• Install a Python through pyenv-win (E.g.: run pyenv install in PowerShell to get latest Python)
• uv python list will abort and complain:

  error: Failed to inspect Python interpreter from search path at `/mnt/c/Users/<user>/.pyenv/pyenv-win/shims/python`
  Caused by: Failed to query Python interpreter at `/mnt/c/Users/<user>/.pyenv/pyenv-win/shims/python`
  Caused by: No such file or directory (os error 2)
  

• uv python list will work again after uninstalling pyenv-win-installed Pythons (Run pyenv uninstall -a in PowerShell)

Note that uv python list in PowerShell works fine with pyenv-win.

Thanks for filing and for the clear repro. We should fix it.

[vdeolali]

Is this fixed yet? I still have this issue from within WSL - when I have pyenv-win installed on PSH

@vdeolali would you be willing to test https://github.com/astral-sh/uv/pull/15315 ? There are binaries attached to the CI summary (at the bottom).
