4-3这一节最后的代码实现出现了问题，cannot import name path

前面全部按照老师讲的写，但是在urls.py这里，老师原本的参数是url，而我的自带的是path，在仿照老师的代码之后，运行报错，我想问一下是不是我的版本不对，我用的python3.6

这是运行后的报错代码，谢谢老师啦~

如果你的Django是2.0版本以上的话，就把 url 改为 path ，按照上面那个范例写就可以了。至于前面那个正则表达式符号 ^ ,个人建议不用写。你可以试一下。

参考代码如下：

urlpatterns = [
    path('admin/', admin.site.urls),
    path('index/', bv.index),
]

补充上面的代码

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

import blog.views as bv

urlpatterns = [
    path('admin/', admin.site.urls),
    path('index/', bv.index),
]
