我在使用templateview时收到此错误

Question

TypeError位于/ 预期的str，字节或os.PathLike对象，而不是元组

我刚刚启动了templateview，CBV，并且即时通讯出现了这个问题

from django.shortcuts import render
from django.views.generic import View,TemplateView
from django.http import HttpResponse

class indexView(TemplateView):
    template_name = 'index.html'

错误：
