我已经安装了模块django-nested-admin .我在使用 django-nested-inline 时也遇到同样的错误而不是 django-nested-admin。知道出了什么问题吗？

在网站上我得到:

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator at root@localhost to inform them of the time this error occurred, and the actions you performed just before this error.

More information about this error may be available in the server error log.

该代码在我们的非 SSL 站点中完美运行。
我已经尝试过 this 中提到的解决方案和 this .没用。任何指针都将非常有帮助。谢谢。

这是我们的 apache 配置文件。这不是实际的，但原始配置与此一致。

Answer 1

这是来自非 ssl 配置的 WSGIDaemonProcess 设置

WSGIDaemonProcess notsslsite processes=2 python-path=/apps/deployment/notsslsite/django_version:/apps/deployment/notsslsite/django_version/env/lib/python2.7/site-packages

这里是ssl配置

WSGIDaemonProcess sslsite processes=2 python-path=/apps/staging/sslsite/django_version:/apps/staging/sslsite/django_version/env/lib/python2.7/site-packages

您对 ssl 和非 ssl 实例使用了不同的 python 路径，可能 nested_admin 没有安装在第二个实例中。这只是在您的 apache 设置中对 django 重要的区别。尝试在 ssl 站点上设置与非 ssl 相同的环境，并检查它是否有效。如果可以，请从 ssl 配置中在环境中安装适当的包。如果它不起作用，可能是您的虚拟环境已损坏，请尝试重新创建它。
