Poetry Hangs Indefinitely Resolving Dependencies

[KyleKing]

• I am on the latest Poetry version
• I have searched the issues of this repo and believe that this is not a duplicate.
  • The only problem that might be related is Poetry install with github private repo gets stuck resolving dependencies indefinitely #2699, but that was for the case of a private repository
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

Issue

Poetry gets stuck resolving dependencies indefinitely. I've let it run for over ten minutes, but resolving dependencies should reasonably take only a few seconds or at least within a minute

I tried uninstalling poetry, different versions of poetry, and removing the .venv and lock file but the problem still exists. I think this could be a problem with my computer, like a cache file or setting that is preventing poetry from accessing a networked resource, but the verbose debugging output doesn't indicate where poetry is held up

Duplicate? #2094

[KyleKing]

Thanks, I think this is the same issue as 2094 and possibly related to #3200 as well

In case anyone else comes here searching, it might also be a pip problem. Setting export PYTHON_KEYRING_BACKEND=keyring.backends.null.Keyring worked for me.
(See pypa/pip#7883)
