Install with Poetry fails with: 'Link' object has no attribute 'name'

Outline

When trying to install click with poetry it fails with the following error:

• Installing click (8.0.3): Failed
  AttributeError
  'Link' object has no attribute 'name'
  at /usr/local/Cellar/poetry/1.1.11/libexec/lib/python3.9/site-packages/poetry/installation/executor.py:632 in _download_link

      630│                         ", ".join(sorted(archive_hashes)),
      631│                         package,

      634│                     )
      635│                 )
      636│ 

I guess this could be an issue with Poetry, but it doesn't seem like it. Seems like click is missing some information in the package that Poetry expects? Install with pip works fine.

Replicate

1. Install Poetry (or simply, brew install poetry on macOS if you have Homebrew).
2. In a virtual environment, run poetry add click

Expected Behaviour

Click should be installed without issues.

Environment: macOS

• Python version: 3.9
• Click version: 8.0.3

This sounds like an issue with Poetry. Please report it to them.

I know nothing about how Poetry works or why archive might not have name in its internals. If it is indeed an issue with Click, I need precise instructions on what needs to be changed.

I searched poetry's issue tracker for "archive name" and immediately found this: python-poetry/poetry#4701

I was searching around in the Poetry issues before submitting this, but didn't find that issue 🤦‍♂️

Seems like Poetry caches some stuff that isn't cleared with the poetry cache command.
Removing ~/Library/Caches/pypoetry did the trick on macOS.

Sorry for the incorrect issue, and thanks for the help!
