Frequently Asked Questions ========================== -Why does flake8 pin the version of pep8? ----------------------------------------- - -Version 1.6 of pep8 doesn't work properly with flake8. Until pep8 releases a -version that works, flake8 pins the version of pep8 so that flake8 will work as -a whole. - -Is flake8 broken? ------------------ - -Flake8 combines two other projects that are significant on their own: pep8 and -PyFlakes. If flake8 is doing something you don't like, it is quite likely that -the problem lies in one of those other projects. You can run them separately -to see if they are the cause of your difficulties. We greatly appreciate your -efforts to diagnose the source of the problem before reporting bugs against -flake8. +Flake8 maintains an `FAQ `_ in its +documentation.
