pdm 2.13.x + pdm-wheel: [TypeError]: expected str, bytes or os.PathLike object, not CachedPackage

[enku]

• 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

set -e
pdm=$(pwd)
pyver=3.12
d=/tmp/pdm-issue
rm -rf $d
mkdir -p $d
python${pyver} -m venv $d/venv
$d/venv/bin/python -m pip install "$pdm"
$d/venv/bin/pdm self add pdm-wheel
mkdir $d/project
cd $d/project
$d/venv/bin/pdm init --non-interactive --python ${pyver}
$d/venv/bin/pdm add setproctitle psycopg gunicorn rq
$d/venv/bin/pdm wheel -v --prod

Actual behavior

pdm wheel --prod fails:

$d/venv/bin/pdm wheel -v --prod
Checking project file...
Checking lockfile...
The lockfile does not contain static file URLs. Exporting wheel may be longer than expected, and 
make calls to indexes.
Use `pdm lock --refresh --static-urls` to include static file URLs in the lockfile.

The exported wheels are no longer cross-platform. Using it them other platforms may cause unexpected

Expected behavior

Prior to pdm 2.13 this operation succeeds and creates wheels in the wheels directory. git bisect points to f7f87bb as the offending commit. I'm not sure, but I don't think the actual packages in the project matter.

I think pdm-wheel is responsible for updating to be compatible with 2.13

[frostming]

I changed my mind, I am going to backport the old build function to not break downstream. Thanks.

[enku]

Thanks. I actually did not realize that pdm-wheel had a different maintainer until you mentioned it.

Maintainer of pdm-wheel here, thanks for the backport :)
