ValueError, whl in cache does not exist when running poetry install again

• I am on the latest Poetry version.

• I have searched the issues of this repo and believe that this is not a duplicate.

• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• Windows 10 1909

• poetry version: 1.2.0a1

Issue

Hey everyone, I’m having issues when trying to run poetry install via jenkins. poetry config virtualenvs.in-project is true. The install fails on the second installation attempt (always). It seems that there is an issue with the way caching works. Here is the trace: Thanks in advance!

Also have this issue with 1.1.8 on Windows 10. My workaround is to go to the path specified, delete the cache and run poetry install again.

e.g.

PS C:\GithubTech\ngx\ngx-cli> poetry install

Go to C:\Users\julie\AppData\Local\pypoetry\Cache, delete everything.

Run poetry install again and:

I found some much better PRs that already had some eyes, not sure what the path to get the PRs merged is.
