在django框架中的python导入错误

Question

from django.contrib import admin
from django.urls import url
from . import views 


urlpatterns = [
    # path('admin/', admin.site.urls),
    url(r'^admin/',admin.site.urls),
    url(r'^about/$',views.about),
    url(r'^$',views.homepage),
]

这是django框架中的python代码。我已经成功安装了django，但我不知道为什么会出现错误。

事实上，我刚开始与django合作，所以请看一下故障。

这可能是因为它无法访问URL和contrib目录。请帮忙，谢谢

Answer 1

尝试使用url的路径，在留档中看到更多，非常好

from django.contrib import admin
from django.urls import path
from . import views 


urlpatterns = [
    # path('admin/', admin.site.urls),
    path('about/',views.about, name='about'),
    path('',views.homepage, name='home-page'),
]

Answer 2

从django导入url。conf.url

from django.conf.urls import url
