flake8 not honoring global configuration. elpy

Question

I am new to emacs & trying to use it for python programming. I have installed elpy & everything is working fine except one thing - I am getting lot of warnings, errors like E401, E402, E501 etc. All are in scary red colors.

After researching little bit, it looks like these errors are coming from flake8. So I configure flake8 as follows:

In ~/.config/flake8,

[flake8]
ignore=E201,E203,E211,E221,E272,E251,E211,E222,E226,E228,E241,E301,E302,E401,E402,E501,E701,F401
max-line-length=160
exclude=tests/*
max-complexity=10

But still those errors are coming. I also configured same way PEP8 & pycodestyle in .config/. But no progress. I tried to put setup.cfg & tox.ini in project root, but that also didn't work.

For more information, there is similar ticket in sublime flake8 repo. https://github.com/SublimeLinter/SublimeLinter-flake8/issues/24

Please let me know if there is any working solution or emacs hacks.

Following are some details

Os - Linux Mint 17.3 Rosa
flake8 version - 3.0.0b1 (pyflakes: 1.2.3, pycodestyle: 2.0.0, mccabe: 0.5.0)
GNU Emacs 24.3.1

Thanks in advance.

Did you try running flake8 directly against the code that you're writing? If you do and have the same problem, can you share the output of flake8 -v – Feoffee

This seems to be broken for me as well. If I have my configuration file in ~/.flake8, and I have my .py files in some subdirectory of ~/, then it picks up the file. This is not expected since I want a global location for this setup, and not have to copy the flake8 configuration settings across all projects I use. – Costermansville

Answer 1

Anyone trying to get this running for flake8>=4.0.0, that's because support for global config file is no longer present, see https://flake8.pycqa.org/en/latest/release-notes/4.0.0.html#backwards-incompatible-changes.

Try restarting emacs. For me it picks up ~/.config/flake8 when emacs is started, but doesn't pick it up between runs.
