PEP 582 CLI erroring with "No command given"

[jarrodli]

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

Steps to reproduce

Run pdm --pep582.

Actual behavior

Errors out with:

$ pdm --pep582 -v
Usage: pdm [-h] [-V] [-c CONFIG] [-v] [-I] [--pep582 [SHELL]]
           {add,build,cache,completion,config,export,fix,import,info,init,install,list,lock,publish,remove,run,search,self,plugin,show,sync,update,use,venv}
           ...
pdm: error: No command given

Expected behavior

This was working in PDM, version 2.4.8. Expected an env setting script. i.e.,

if test -n "$PYTHONPATH"
    set -x PYTHONPATH '/opt/homebrew/lib/python3.11/site-packages/pdm/pep582' $PYTHONPATH
else
    set -x PYTHONPATH '/opt/homebrew/lib/python3.11/site-packages/pdm/pep582'
end
