  • 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).

Issue

Removing {markers = "sys_platform == 'win32'", path = "./wheels/python_ldap-3.4.0-cp310-cp310-win_amd64.whl"} fix error.
Why file not python-ldap (>=3.1) is satisfied by python-ldap (3.4.0 wheels/python_ldap-3.4.0-cp310-cp310-win_amd64.whl) on linux cause exception? But before everything worked, why this error began to occur now I don’t know, I didn’t change anything regarding this.

This is not reproducible as the problematic constraint requires a wheel file that reproducers do not have. Closed as it looks like the problematic behavior should be addressed now, anyway.
