module 'lazr' breaks pydeps

Tested on Linux, Ubuntu 20.04.

Consider this oneliner test program test_pydeps.py:

import lazr

Run pydeps on it. It will give an enormous stacktrace, this is the tail:

  File "/home/jan/.local/lib/python3.8/site-packages/pydeps/py2depgraph.py", line 139, in import_module
    module = mf27.ModuleFinder.import_module(self, partnam, fqname, parent)
  File "/usr/lib/python3.8/modulefinder.py", line 318, in import_module
    fp, pathname, stuff = self.find_module(partname,
  File "/usr/lib/python3.8/modulefinder.py", line 510, in find_module
    return _find_module(name, path)
  File "/usr/lib/python3.8/modulefinder.py", line 79, in _find_module
    if spec.loader.is_package(name):
AttributeError: 'NoneType' object has no attribute 'is_package'

Excepted result: a more descriptive error or warning, mentioning lazr, perhaps guiding the user to exclude it?

I ran into this problem when I tried to analyze my own project. Had to sprinkle some print statements in pydeps to figure out that lazr was the problem.

Workaround which works fine for me: just exclude lazr.

PS: I have no clue what lazr is, how it found its way onto my system, and why it is so special for pydeps; I just happen to implicitly use it in my project.

Solved indeed, many thanks!

This should be fixed in the latest version (v1.10.17) available on PyPI.
