林学习Django的，所以我装盘做我firts Django项目，所以我遵循一些简单的和默认的步骤，首先创建一个ENVIRO，然后简单做一个“manage.py迁移”命令。

我不知道我必须在urls.py文件的第20行中更改什么：

"""miWeb URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/2.0/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  path('', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.urls import include, path
    2. Add a URL to urlpatterns:  path('blog/', include('blog.urls'))
"""
from django.contrib import admin
from django.urls import include, re_path

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

Answer 1

路径和re_path两者在不同的模块django.urls 。

您正在导入re_path并使用path

将代码更改为

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

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

如果要同时使用path和re_path同时导入。

from django.urls import include, path, re_path
