ValueError: min() arg is an empty sequence

[leibowitz]

• 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

pdm install. I have a massive pyproject.toml which I've been trying to narrow down, to find the dependencies to reproduce the issue. Will update the issue later once I get that

Actual behavior

Error occurs
