  Target Milestone: ---

There is a couple(or more than couple) of packages on PyPi that doesn't work
with the scanpypi script (for example wheel/importlib_resources). The reason of
that is that it uses setup.cfg in conjunction with setup.py to package metadata
configuration. Use of scanpypi on these packages fails with the following
errors:

utils/scanpypi:23: DeprecationWarning: the imp module is deprecated in favour
of importlib; see the module's documentation for alternative uses
  import imp
spdx_lookup module is not installed. This can lead to an inaccurate licence
detection. Please install it via
pip install spdx_lookup
