Error in sitecustomize; set PYTHONVERBOSE for traceback: AssertionError: assert not path in sys.path

[markp2]

Unfortunately I have this issue after upgrading pip and setup tools in my non venv environment (brew). Using the -v flag I can see there is an Error in sitecustomize; If I set PYTHONVERBOSE for traceback I see the 2 python Tracebacks in addition to the pip ERROR: No matching distribution found for xmlsec==1.3.12

  Traceback (most recent call last):

Is there a way for me [or you] to modify the assert line to show the paths:

assert not path in sys.path, (path, sys.path)

[markp2]

Found the assert line - it originates in file python3.10/site-packages/pip/_internal/build_env.py

I then modified this file to show the assertion:

assert not path in sys.path, (path, sys.path).

Running now shows this error:

AssertionError:

)

Is this a pip or xmlsec install issue - asserting that '/usr/local/lib/python3.10/site-packages' should not be in sys.path? For example does xmlsec override PYTHONPATH?

[hoefling]

The assertion error is negligible since it doesn't abort the installation. For now it looks like an issue with setuptools-scm to me. What is the output of pip install 'setuptools-scm<7' && pip install xmlsec --no-build-isolation?
