PET fails with pyenv shims

[dabljues]

Hey.

When running pet find, I get many errors regarding pyenv shims:

If I remove the shims from the path, the search is orders of magnitude quicker + the pyenv environments number found doesn't change (meaning I guess PET found pyenv envs):

The problem is, pyenv docs explicitly say that the shims should be in PATH: https://github.com/pyenv/pyenv?tab=readme-ov-file#nushell. I guess my question is: should this be happening? Because a slowdown like this is noticeable (when for example PET is used by an editor). Maybe I have misconfigured something?

@dabljues
Please can you share the following information

• Values of the following env variables
  • PYENV
  • PYENV_ROOT
  • PATH
    You can use echo $PYENV_ROOT to get the values

For PATH I'm only interested in finding out all occurrences of paths that are specific to pyenv (hence no need to share everything)

• Please run the following ~/.cargo/bin/pet find --verbose & share the full logs ( I would like to see when and why python is spawned)
  Please do share the full logs, if you remove something due to privacy issues or the like, please obfuscate instead of removing it)
