'poetry install' command fails; *.whl files are not found

 python - 'poetry install' command fails; *.whl files are not found - Stack Overflow

According to https://github.com/python-poetry/poetry/issues/4163, it seems to be an issue still pending to be resolved.

As a workaround, dumping dependencies to a requirements.txt file via poetry:

$ poetry export -f requirements.txt --output requirements.txt --without-hashes

and then installing them via pip, worked for me:

$ pip install -r requirements.txt

Specifically I found that deleting the AppData\Local\pypoetry\Cache\artifacts folder (I'm on Windows 10) worked for me. virtualenvs for other projects may be in AppData\Local\pypoetry\Cache\virtualenvs so you might not want to delete the root cache folder at AppData\Local\pypoetry\Cache in its entirety.
