django RESTframework教程的问题

我试图熟悉django RESTFramework，因此我开始了官方教程，以创建测试API

当最终通过[CMD]“pyhon manage.py runserver”在我的Windows上启动API时，我在命令行上得到一个错误代码，您将在下面看到

我还想补充一点，不幸的是，教程中的描述存在一些模糊性，至少从初学者的角度来看是这样的，也就是说，并不总是确定教程中的相应代码是否正确 需要在模块中添加或替换模块中的全部或部分代码

因此，我尝试以各种方式实现本教程的指导，总是有相同的最终结果

我正在一个虚拟环境中运行代码，在那里我安装了Django 1.11.，所以不同的Django版本应该不会有问题

“views.py”

“url.py”

在“settings.py”中，我添加了“rest\u framework”

# Application definition

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles'
    'rest_framework',
]

最后我还添加了以下代码：

REST_FRAMEWORK = {
'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.PageNumberPagination',
'PAGE_SIZE': 10
}

很可能您正在使用的是django2.0。从django 2.0开始，

include

在驻留在

django.conf.urls

（）之前已移动到

django.urls

。因此，您需要像这样更新

url.py

：

        from django.conf.urls import url, include
        from django.contrib import admin
        from rest_framework import routers
        from tutorial.quickstart import views

        router = routers.DefaultRouter()
        router.register(r'users', views.UserViewSet)
        router.register(r'groups', views.GroupViewSet)

        urlpatterns = [
            url(r'^admin/', admin.site.urls),
            url(r'^', include(router.urls)),
            url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework'))
        ]

您不能同时使用

path

，因为它也是

或者您可以移动到django>2.0，但在这种情况下，您必须从django.conf.url导入url中删除

，并使用django.url导入url中的
谢谢！我想知道，为什么pip安装了django 1.11而不是django 2.x。。。也许，因为我用的是python2.7？
