Django，gunicorn，nginx 抛出 504 Gateway Time-out: AttributeError: module 'static' has no attribute 'Cling'

Question

昨天我在线部署了我的小网站的新版本，并立即收到 504 Gateway Time-out 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

    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 dj-static 已正确安装。

什么可能导致这个问题？ 提前致谢

编辑：

当我在本地运行生产设置时，一切正常。但是，当我尝试在生产服务器上运行它们时（不是使用 gunicorn，而是使用 django 自己的运行服务器），我得到的错误与我在 gunicorn 错误日志中收到的错误相同（请参阅上面的错误）。

我也运行本地设置，它们也会引发上述错误。

编辑 2： 我已经创建了一个新环境并重新安装了需求文件，但错误仍然存​​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"

它必须有效。

我假设您使用pipenv 来创建项目环境。
