Django，gunicorn，nginx抛出504网关超时: AttributeError:模块‘静态’没有属性'Cling‘

Question

昨天，我在网上部署了一个新版本的小网站，并立即收到504网关超时错误。

在对日志文件进行了一些挖掘之后，我发现了以下错误：

File "/home/dev/venuepark/ENV/lib/python3.6/site-packages/django/utils/autoreload.py", line 225, in wrapper
    fn(*args, **kwargs)
  File "/home/dev/venuepark/ENV/lib/python3.6/site-packages/django/core/management/commands/runserver.py", line 137, in inner_run

    super(MediaCling, self).__init__(application, base_dir=base_dir)

    self.cling = static.Cling(base_dir)
AttributeError: module 'static' has no attribute 'Cling'

我的wsgi.py：

import os

from django.core.wsgi import get_wsgi_application
from dj_static import Cling, MediaCling

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'venuepark.config.settings.production_settings')

application = Cling(MediaCling(get_wsgi_application()))

但是dj-静态是正确安装的。

是什么导致了这个问题？提前感谢

编辑：

当我在本地运行生产设置时，一切正常。但是，当我试图在生产服务器上运行它们时(不是使用gunicorn，而是django自己的运行服务器)，我得到的错误与在我的gunicorn错误日志中接收到的错误相同(参见上面的错误)。

我也运行本地设置，它们也会引发上面的错误。

编辑2:我已经创建了一个新的环境并重新安装了需求文件，而且错误仍然存在。AttributeError: module 'static' has no attribute 'Cling'

Answer 1

再次检查您的环境创建：

mkdir /tmp/djstatic && cd /tmp/djstatic
pipenv install django dj_static
pipenv run python -c "from dj_static import Cling"

一定会成功的。

我认为您使用pipenv来创建项目环境。
