Comparison of str < None on Python 3

[jodal]

I'm running flake8-import-order on Python 3.4:

$ flake8 --version
2.2.2 (pep8: 1.5.7, import-order: 0.4.2, pyflakes: 0.8.1, mccabe: 0.2.1) CPython 3.4.0 on Linux

And it crashes because of a comparison of str and None:

$ flake8 
Traceback (most recent call last):
  File "/home/jodal/dev/virtualenvs/vega3/bin/flake8", line 11, in <module>
    sys.exit(main())
  File "/home/jodal/dev/virtualenvs/vega3/lib/python3.4/site-packages/flake8/main.py", line 32, in main
    report = flake8_style.check_files()

    self.input_dir(path)

    self.check_ast()

    if n < pn:
TypeError: unorderable types: str() < NoneType()

But it works when running flake8 with Python 2.7 on the same code base:

$ flake8 --version
2.2.2 (pep8: 1.5.7, mccabe: 0.2.1, import-order: 0.4.2, pyflakes: 0.8.1) CPython 2.7.6 on Linux
$ flake8 
$ echo $?
0

Any chance you can figure out the file it's linting when it crashes? This plugin is used on several Python 3 projects where it works fine.

Running flake8 on Python 3:

from . import a
from .x import b

Very likely that this is not failing in Py2 because everything is larger than None there.

Will do a release Soon (tm).
