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.
