Django “无法导入名称 PMMail”

Question

我有点卡住了。

我在我的Mac上配置一个项目，之前在同一台电脑上也做过这个项目，但现在我把电脑格式化了。

当我尝试运行 python runserver 时，一切正常，但当我在浏览器中加载它时，就出现了这个：

而在终端中我得到了这个：

$ python manage.py runserver
Validating models...

编辑

这是我在 settings.py 中的中间件类

MIDDLEWARE_CLASSES = (
'debug_toolbar.middleware.DebugToolbarMiddleware',
'quizzer.views.FacebookMiddleware',
'django.middleware.common.CommonMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'quizzer.middleware.SetGroupMiddleware',
'quizzer.django-crossdomainxhr-middleware.XsSharing',

# Uncomment the next line for simple clickjacking protection:
# 'django.middleware.clickjacking.XFrameOptionsMiddleware',
)
