Issue

(I managed to solve the problem, but still decided to report this as I suppose this may be a solution to some hash&cache related issues)

I encountered an internet connection problem during installing NumPy to a new poetry environment, manually closed the poetry command window, and retried poetry install after regaining internet connection, but got

Invalid hashes (sha256:81efafdaee436f1f34e9121d9ea96fa95d20c73390cd2874fe3ffc75cc86425a) for NumPy (1.23.1) using archive NumPy-1.23.1-cp39-cp39-win_amd64.whl.

Like the suggestions related to hash resolve issues, I tried poetry cache clear . --all, poetry cache clear --all pypi and deleting poetry.toml, but I still got the same RuntimeError.
Then I tried to find the .whl document and found it in

C:\Users\(username)\AppData\Local\pypoetry\Cache\artifacts...

After that I deleted all documents in artifacts directory, and then everything goes smoothly.
It seems that on windows the cache clear command only removes caches in C:\Users\(username)\AppData\Local\pypoetry\Cache\\**cache**, but the artifacts document on the same level with "cache" is untouched. I believe some cache-related problems that couldn't be solved by running poetry cache clear are related to this.
