[Bug]: Unable to start mcpm #271
Description
What happened?
When I used pipx install mcpm and ran mpc --version, I encountered the following error:
TypeError: cannot specify both default and default_factory
I think this might be a bug. I've tested it on both debian 13 and gentoo and was able to reproduce the issue. How should this be resolved?
What did you expect?
I hope to get help
MCPM Version
