Apache2＆Django-NameError：名称“ AttributeError”未定义

Question

我几乎遵循了所有官方文档，以使Django项目在Ubuntu 18.04 v服务器上运行。它似乎可以正常工作... sudo service apache2 status->一切都还可以。

我首先注意到，如果不重新启动服务器就无法更新模板，这将是Django的惯常行为（即使在生产环境中也是如此）。每当我重新启动服务器时，都会在apache2 / error.log中收到此错误。尽管服务器保持运行，但我想深入了解这一点。

[任何建议可能有什么问题，为什么它说“找不到AttributeError？”当它似乎是一个现成的标准python类时，谢谢您的帮助：-）
