after that it's the same error

[tobych]

The exception is being raised in this line:

pythonfinder/src/pythonfinder/models/python.py

Line 165 in ef356f7

version_entry = next(iter(entry.find_all_python_versions()), None)

Looks like this is happening because the exception handler is assuming version_path is not None. And version_path will be None if bin_dir.exists() is falsey. I've not looked into this more as I'm actually just trying to get pipenv working for me, which includes pathfinder in the package.

I got things working for me by adding this code at the top of the exception handler, immediately before line 165:

if version_path is None:
    continue

Can you bother to confirm if this is still an issue @tobych

[frostming]

No longer an issue
