Question

我在网上搜索了其他解决方案但运气不佳。在这里发布是最后的手段。

我的Django项目一切都运行良好。然后突然它像以前一样停止运行服务器。我完全不确定我做错了什么。

这个问题在所有git分支中都是持久的（以前它不是这样的） - 因为问题不是仅仅分离到我的分支而使它更加混乱。

以下是错误追溯：

    WARNINGS:
?: (1_7.W001) MIDDLEWARE_CLASSES is not set.
    HINT: Django 1.7 changed the global defaults for the MIDDLEWARE_CLASSES. django.contrib.sessions.middleware.SessionMiddleware, django.contrib.auth.middleware.AuthenticationMiddleware, and django.contrib.messages.middleware.MessageMiddleware were removed from the defaults. If your project needs these middleware then you should configure this setting.

另外，请注意我尝试在settings.py中更改为MIDDLEWARE_CLASSES [...] - 但它没有帮助。

这是settings.py：

重申一下。这突然出现了。不知道是什么造成的。

谢谢。

Answer 1

它出现了，因为项目中的某些内容发生了变化，现在迁移失败了。

在错误日志中，您可以看到

  File "C:\Users\ASUS\PycharmProjects\5CCS2SEG_Major\connect_therapy\migrations\0021_auto_20180313_1946.py", line 4, in <module>
    import django.contrib.auth.base_user
ModuleNotFoundError: No module named 'django.contrib.auth.base_user'

迁移的作用是什么？仍然有效或项目已更改，迁移是否尝试加载不再可用的资源？

如果您运行python manage.py shell，您是否可以从'django.contrib.auth.base_user'导入？问题似乎在于迁移

Answer 2

最后的“解决方案”是创建一个新的虚拟环境。出于某种原因，老人搞砸了。

服务器启动时出现Django异常 - 找不到模块
