flake8 not picking up config file

Question

I have my flake8 config file in ~/.config/flake8

[flake8]
max-line-length = 100

However when I run flake8 the config file is not picked up. I know that because i still get warnings over lines longer than 79 char.

I'm on redhat, but the same happens on mac.

I use pyenv. Global is 2.7.6 (not even sure this is relevant)

Answer 1

I had a silly mistake, leaving out the [flake8] tag at the beginning of my configuration file I just spent 2 hours debugging this problem.

Here was my original .flake8 file:

ignore=
    # line too long
    E501,
    #line break after binary operator
    W504

This was the fix:

[flake8]
ignore=
    # line too long
    E501,
    #line break after binary operator
    W504

Obviously this wasn't OP's problem: they have the tag in there. But if I can save one person from my stupidity, I will be happy. Frankly I was almost too embarrassed to post this because it is an "Is your computer plugged in?" level error, but oh well.

Answer 2

Sharing my mistake in case this can help someone:

I had a similar issue which was simply due to a bad file name: .flake8.txt instead of .flake8.

Correcting resolves the issue.
