  • I have searched the issue tracker and believe that this is not a duplicate.

Make sure you run commands with -v flag before pasting the output.

Steps to reproduce

  1. pdm init
    1. Select python 3.10
  2. pdm add gevent

Create a new project and adding gevent does not work.

Actual behavior

pdm add gevent

Sorry for that, it has been fixed in 1.12.5. You will need to pdm lock then pdm install
