"Failed to create Python virtual environment" because of unknown missing file

### Summary

Just testing out prek with Nix, and it's working great locally. But [in CI I get the following error](https://gitlab.com/engmark/root/-/jobs/13305020918):

```
error: Failed to install hook `pretty-format-ini`
  caused by: Failed to create Python virtual environment
  caused by: Run command `create venv` failed
  caused by: No such file or directory (os error 2)
```

### Willing to submit a PR?
