TypeError: cannot unpack non-iterable NoneType object

With python-inspector 0.7.0, when running python-inspector --python-version 310 --json-pdt - --requirement requirements.txt on this file I get this error:

Traceback (most recent call last):

The same happens with python-inspector --python-version 27 --json - --setup-py setup.py and this file.

72.json.txt @mnonnenmacher I was not able to reproduce this error for requirements.txt, uploading the result here

[TG1999]

@mnonnenmacher I ran the command with the verbose flag like this python-inspector --python-version 27 --json - --setup-py setup.py --verbose and it threw this error Exception('Unable to collect setup.py dependencies securely'), then I ran it with the insecure flag like this python-inspector --python-version 27 --json - --setup-py setup-1.py --analyze-setup-py-insecurely and got this
72-setup-py.json.txt

@TG1999 Thanks, that works for me as well. I think it would be great if the tool would print a meaningful error message also without the --verbose flag.

@mnonnenmacher we can have an issue to track this if you want.

[mnonnenmacher]

@pombredanne Yes, that would be nice, I think that would be a better UX.
