我是第一次使用 Django，我正在尝试构建一个 API，我正在按照一些教程和示例进行操作，它工作正常，但是在安装所有要求和项目后，我现在正在 Raspberry Pi 中运行该项目失败并出现以下错误：

AttributeError: type object 'SessionViewSet' has no attribute 'get_extra_actions'
我的 views.py 有以下代码：
from django.shortcuts import render
from rest_framework import viewsets
from .models import Session
from .serializers import SessionSerializer
from rest_framework.views import APIView, Response
class SessionViewSet(APIView):
queryset = Session.objects.all()
serializer_class = SessionSerializer
def get(self, request, format=None):
return Response("test")
我真的不知道为什么在我的笔记本电脑上工作，但在我的 Raspberry Pi 上却不工作。
这是否发生在某人身上或任何人都知道为什么会发生这种情况？
太感谢了！
编辑：
这是我的 urls.py
from django.conf.urls import url
from rest_framework import routers
from openvpnmonitor.api.views import SessionViewSet
router = routers.DefaultRouter()
router.register(r'sessions', SessionViewSet)
urlpatterns = [
url(r'sessions', SessionViewSet.as_view()),
url(r'^docs/', schema_view),
]
urlpatterns += router.urls

您称它为视图集，但这并不能使它成为一个视图集；您继承自 APIView，它是一个独立的通用视图，而不是视图集。
viewset需要继承viewsets.ViewSet。
