    template_name = 'main/index.html'
    config = None

    updated = models.DateTimeField(_('change date'), auto_now=True)

    class Meta:

from django.apps import AppConfig

尝试添加as_view并更好地显示完整的错误跟踪

urlpatterns = [
    # url(r'^$', views.IndexView.as_view(), name='index' ),
    url(r'^$', views.IndexView.as_view(), name='index'),
    #                          ^^^^^^^^
]
