Successfully suppresses the warnings for me too. Thanks!
Used the same commands as @Molkree to test. Here is the procedure, in case it matters:
- Using the old pip (which shows the warnings):
pip install -U git+https://github.com/uranusjr/pip.git@locations-deb-system-prefix
- Force reinstall using new pip. It will build the package again since repo is specified. No warnings are shown now.
pip install -U --force-reinstall git+https://github.com/uranusjr/pip.git@locations-deb-system-prefix

It turns out this is a bug in Debian’s
distutils.sysconfig.get_python_lib()implementation. This function is called when pip builds a package from source (to create a build-time isolated environment), so it does not happen when you install a wheel (or when installing a package from source for a second time, because pip would cache the previously-built wheel). This patch basically just tries to detect that bug and pretend nothing happens when it triggers the warning.Please give this a try and tell me if it can correctly suppress the warning.
