flake8 Version Conflict with pep8 1.6.2 (current version) about sublimelinter-flake8

[groteworld]

Does flake8, the command line tool, itself work with the new pep8 installed?

Yes it does.

I've got the same problem with pyflakes at the moment, but also had it with pep8 at times:

Traceback (most recent call last):

I've got these versions of flake8, pyflakes, pep8, pep257 and mccabe installed:

• flake8: 2.4.1
• mccabe: 0.3.1
• pep257: 0.6.0
• pep8: 1.6.2
• pyflakes: 1.0.0

Works without any problems when calling flake8 directly, but the linter plugin does not work, likely due to the pkg_resources.load call, which checks install_requires. flake8 has these versions defined in its setup.py:

    install_requires=[
        "pyflakes >= 0.8.1, < 0.9",
        "pep8 >= 1.5.7, != 1.6.0, != 1.6.1, != 1.6.2",
        "mccabe >= 0.2.1, < 0.4",
    ],

But since it still works when using it directly, why does the linter plugin need to do this check?

I got around this problem by downgrading pep8 to version 1.5.7, as described in this StackOverflow post.

It seems that flake8 has blacklisted recent versions of pep8.
