问题

我收到了数千个源自本地 .env 的 flake8 错误。一些错误消息的示例：

./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:3855:65: E202 whitespace before ')'

./env/lib/python3.7/site-packages/pip/_vendor/pyparsing.py:3858:78: E202 whitespace before ')'
./env/lib/python3.7/site-packages/pip/_vendor/pyparsing.py:3861:31: E231 missing 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

我的目录如下所示：

我的 flake8 文件如下所示：

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

问题

如何将我的 env 文件内容添加到 flake8 的排除列表中？

我尝试过的

我已经尝试添加：

  env,
./env,

我试过去掉逗号并添加：

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

运行 flake8 --exclude 迁移，pycache，manage.py，settings.py，env 返回：

【问题讨论】：

您是否尝试过使用env？结果一样吗？
谢谢卢卡斯，但我有。我将更新问题以包含此
或者更确切地说是.env/ ?
我刚才也试过了。我会将其添加到尝试过的内容中。
您可以尝试在命令行中提供排除模式吗？ flake8 --exclude migrations,__pycache__,manage.py,settings.py,env

标签： python django flake8

【解决方案1】：

我注意到您的 .flake8 文件位于 app 文件夹中。我假设您是从 app 文件夹外部启动 flake8，换句话说，从项目根目录开始。

将.flake8 移动到项目根目录，一切正常：

mv app/.flake8 .

【解决方案2】：

删除逗号。这些 .ini 文件中的列表只是多行列表：

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

【讨论】：

感谢 AKX，但它似乎没有任何改变，我仍然收到错误
你的目录也叫env，而不是.env :)
哈哈，我正在尝试使用 env .env ./env env/ .env/ ！

【解决方案3】：

也可以通过cli的--exclude标志排除。

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

注意这里是逗号分隔的列表，与 flake8 配置文件不同
