Question

我刚刚将我的Django升级到版本1.9.6。我正在做basic tutorial，但我在urls.py中有一个语法错误。

注意：我将名称“mysite”更改为“polls”，并将“polls”更改为“poll”。

这是我在polls / poll / urls.py中的代码：

from django.conf.urls import url

from . import views

urlpatterns = [
    url(r'^, views.index, name='index'),
]

这是错误消息：

感谢您的帮助

Answer 1

您错过了'来结束字符串（在r'^,中的逗号之前。理想情况下，您还应添加$：

url(r'^$', views.index, name='index'),

请注意，您的文本编辑器或IDE可能会进行语法突出显示以帮助您发现此问题 - 请注意，在您的问题中，Stack Overflow的所有^, views.index, name=都采用相同的颜色，以表明它是＆＃39; sa单串。
