curl -fsSL <script_url>|python3 - -v HEAD

But I doubt if it is installed with curl, the error tells me the library is from:

/Users/luxing/opt/anaconda3/lib/python3.9/site-packages/pep517/in_process/_in_process.py

It depends on how you installed PDM. It seems you used anaconda, then:

/Users/luxing/opt/anaconda3/bin/python -m pip install -U "pdm @ git+https://github.com/pdm-project/pdm.git@main"

It should work just copy and paste
