Django - 不正确配置：模块“django.contrib.auth.middleware” [英] Django - ImproperlyConfigured: Module "django.contrib.auth.middleware"

问题描述

我正在运行一个virtualenv来尝试学习Django，但是无论什么原因，安装Django之后，当我尝试访问默认的Django起始页时，我在浏览器中收到以下错误：

I'm running a virtualenv to try to learn Django, but for whatever reason after installing Django and when I try to access the default Django start page, I get the following error in the browser:

发生服务器错误。请联系管理员。

A server error occurred. Please contact the administrator.

在运行服务器的终端窗口中显示以下错误：

In the terminal window where I am running the server says the following error:

不正确配置：模块django.contrib.auth.middleware未定义SessionAuthenticationMiddleware属性/类

ImproperlyConfigured: Module "django.contrib.auth.middleware" does not define a "SessionAuthenticationMiddleware" attribute/class

如果有任何人有任何见解，为什么我在virtualenv中得到这个错误，我会很感激。我可以让服务器在非virtualenv设置中正常运行。

If anyone has any insight as to why I'm getting this error in the virtualenv, I'd appreciate it. I can get the server to run correctly in a non-virtualenv setup, though.

这是完整的堆栈跟踪：
