如果还有其他问题需要回答，请告诉我，我是框架和django的新手。所以我真的不太了解它。

我和你有同样的问题。我试着改变网址：
url(r'^accounts/', include('registration.backends.simple.urls')),
希望这会有所帮助。
答案 1 :(得分：0)
我认为您安装了错误版本的Django注册。
回溯包含
/registration/backends/model_activation/views.py in register
然而，django-registration-redux中不存在model_activation后端（请参阅GitHub上的the directory）。我认为你安装了django-registration（而不是redux）2.x。
如果您正在阅读教程，确保安装了软件包和版本非常重要，否则您将遇到类似的问题。
答案 2 :(得分：0)
完全删除您的数据库。在您的情况下，请删除与db.sqlite3位于同一文件夹中的manage.py。将.py文件保留在<your app>/migrations文件夹中，不要删除它们。
然后运行python manage.py migrate
然后在数据库中再次设置所有数据。
