Unsure what to do with 'Error processing line 3 of ...' errors occuring with pdm install, but not pip install -r

[lestephane]

I have dependencies

google-cloud-vision<2.0.0
requests

And am getting a few errors with pdm install that I don't get with pip install -r + requirements.txt.
The pdm errors seem to have no effect on the outcome, and pdm reports 🎉 All complete!.
What do these errors mean?
