Exclude .env directory from flake8 tests?

问题

Problem

I'm getting thousands of flake8 errors stemming from my local .env. An example of some of the error messages:

./env/lib/python3.7/site-packages/pip/_vendor/pyparsing.py:3848:80: E501 line too long (85 > 79 characters)
./env/lib/python3.7/site-packages/pip/_vendor/pyparsing.py:3848:84: E202 whitespace before ')'
./env/lib/python3.7/site-packages/pip/_vendor/pyparsing.py:3855:51: E201 whitespace after '('

./env/lib/python3.7/site-packages/pip/_vendor/pyparsing.py:3865:1: W293 blank line contains whitespace
./env/lib/python3.7/site-packages/pip/_vendor/pyparsing.py:3866:1: E302 expected 2 blank lines, found 1

My directory looks like this:

My flake8 file looks like this:

[flake8]
exclude =
    migrations,
    __pycache__,
    manage.py,
    settings.py,

Question

How can I add my env file contents to the exclude list in flake8?

What I've tried

I've tried adding:

  env,
./env,

I've tried taking off commas and adding:

[flake8]
exclude =
    migrations
    __pycache__
    manage.py
    settings.py
    env
    .env
    ./env
    env/
    .env/

Running flake8 --exclude migrations,pycache,manage.py,settings.py,env returns:

回答1:

I notice your .flake8 file is inside app folder. I presume you are starting flake8 from outside the app folder, in other words from the project root.

Move .flake8 to the project root, and everything's gonna work:

mv app/.flake8 .

回答2:

Remove the commas. Lists in these .ini files are simply multi-line lists:

[flake8]
exclude =
    migrations
    __pycache__
    manage.py
    settings.py
    env
    .env

回答3:

It's also possible to exclude via --exclude flag of the cli.

 --exclude patterns    Comma-separated list of files or directories to
                    exclude. (Default: ['.svn', 'CVS', '.bzr', '.hg',
                    '.git', '__pycache__', '.tox', '.eggs', '*.egg'])

note that here it is a comma-separated list, unlike in the flake8 config file
