Poetry | AttributeError 'Link' object has no attribute 'name' - python-poetry

Question

I want to install packages from poetry.lock file; using poetry install.
However, the majority of packages throw the exact same error, indicating a shared fundamental problem.
What is causing this? What is the standard fix?
Specification:
Windows 10,
Visual Studio Code,
Python 3.8.10 & Poetry 1.1.11,
Ubuntu Bash.
Terminal:
rm poetry.lock
poetry update
poetry install
me#PF2DCSXD:/mnt/c/Users/user/Documents/GitHub/workers-python/workers/composite_key$ poetry update

Please let me know if there is anything else I can add to post.

Answer 1

In my case (poetry 1.1.6) I solved it by clearing the artifacts cache before poetry install:
rm -rf $HOME/.cache/pypoetry/artifacts/*

Answer 2

This looks to be an active issue relating to poetry. See here - Issue #4085. Some suggest a workaround by downgrading poetry-core down to 1.0.4.
There is an active PR to fix the issue.
