django2版本的include怎么用呢？

Question

这是项目blog里面的url.py

from django.urls import path
from . import views
urlpatterns = [
    path('', views.index, name="index"),
]

这是根目录里面的url.py

from django.contrib import admin
from django.urls import include, path

urlpatterns = [
    path('blog/', include('blog.urls')),
    path('admin/', admin.site.urls),
]

下面是报错信息

Answer 1

将blog文件夹url.py下命名改成 urls.py

Answer 2

用法没错，我估计你是忘记修改INSTALLED_APPS了

Answer 3

from django.contrib import admin
from django.urls import include, path

maybe the path should be:
from django.conf.urls import include,url

have a try, Good luck.

Answer 4

看下 INSTALLED_APPS 里有没有把你自己的 app 加进去
