Flake8 does not respect mypy.ini

[tsoernes]

I have a mypy.ini file at project root, with Python version set to 3.7.. Running flake8 on any file in that directory still gives me T499 mypy: error: failed to find a Python executable matching version (3, 6). Running mypy standalone works straight out of the box, with or without mypy.ini, without any additional arguments or configuration.

$ which flake8
~/anaconda3/bin/flake8
$ which python
~/anaconda3/bin/python
$ python ~/anaconda3/bin/flake8 multipuller/feed.py

(The problem with using --mypy-config is that is does NOT work in subdirectories)

Have also tried adding this to setup.cfg, without luck:

#[mypy]
#python_version = 3.7

Also fixed by https://github.com/ambv/flake8-mypy/pull/22/files

Try from master!

Although this will only fix the problem for the version. In case you wanna check for another platform than linux, I'm afraid that the problem remains...
