python - ImportError：无法从“rest_framework”导入名称“路由器”

Question

我刚开始学习 Django REST 框架。我正在尝试完成官方文档中的快速入门。我收到此错误：

Exception in thread django-main-thread:

    from rest_framework import routers
ImportError: cannot import name 'routers' from 'rest_framework' (F:\Programmi
ng\Python\rest_framework\rest_framework\__init__.py)

网址.py

from django.contrib import admin
from django.urls import path, include
from rest_framework import routers
from quickstart import views

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



urlpatterns = [
    path('admin/', admin.site.urls),
    path('api-auth/', include('rest_framework.urls', namespace='rest_framework'))

]

视图.py

from django.shortcuts import render
from django.contrib.auth.models import User, Group
from rest_framework import viewsets, permissions
from quickstart.serializers import UserSerializer, GroupSerializer


class UserViewSet(viewsets.ModelViewSet):
    """API endpoint that allows users to be viewed or edited."""
    queryset = User.objects.all().order_by('-date_joined')
    serializer_class = UserSerializer
    permission_classes = [permissions.IsAuthenticated]

class GroupViewSet(viewsets.ModelViewSet):
    """API endpoint that allows groups to be viewed or edited."""
    queryset = Group.objects.all()
    serializer_class = GroupSerializer
    permission_classes = [permissions.IsAuthenticated]

当然，我已经安装了 Rest Framework 和 Django。如果有帮助，我正在使用 Python 3.7.9。我已将其余框架添加到我安装的应用程序中：.

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

我已经检查了有关路由器等的官方文档，它们以与我相同的方式导入路由器，但由于某些奇怪的原因我的不起作用。可能是什么问题？

谢谢您的帮助！:)
