Support egg/zip files

[Syndorik]

Environment data

• Language Server version: 2021.5.2-pre.1
• OS and version: Windows
• Python version (& distribution if applicable, e.g. Anaconda): Conda

Expected behaviour

When I do

conda install -c huggingface transformers

It installs to my environement an eggfile. Autocompletion doesn't work with them, while it works for usual installations

Thanks for the issue; we currently don't support egg/zip files (which python transparently opens). We'd need to add support to open these as directories in our file system abstraction.

[jakebailey]

Hm, you say egg-link files; those should work already. Can you please include trace logs our template asks for? This would indicate that python isn't giving us the list of paths correctly.

(Basically, .egg and .zip aren't yet supported, but .egg-link is something that Python will stick into sys.path which we do use.)

[Syndorik]

Oh sorry, I'm fairly new to this, so I might have misunderstood egg-link and egg files. I have two files in my site-package:
transformers-4.5.1-py3.8.egg
transformers.pth

Are these supported?

[jakebailey]

Ah, no, those are plain old egg files (which are just zips). We don't support those quite yet.

[jakebailey]

Retitled to match for better tracking.

Ok thanks for your answer!
