python - 尝试使用 django rest 框架运行 django 时没有名为 http_client 的模块错误

Question

我正在尝试使用 django rest 框架创建一个简单的 API。在 View 中，我有以下代码。

    from django.shortcuts import render
from moviestash.models import Movie
from moviestash.serializer import MovieSerializer
from rest_framework import generics

#List all movies and add movies
class MovieList(generics.ListCreateAPIView):
    queryset = Movie.objects.all()
    serializer_class = MovieSerializer

#Get a movie and delete a movie
class MovieDetail(generics.RetrieveDestroyAPIView):
    queryset = Movie.objects.all()
    serializer_class = MovieSerializer

当我运行服务器并尝试转到任何 url 时，我收到以下错误。

Request Method: GET
Request URL: http://127.0.0.1:8000/

Exception Type: ImportError at /
Exception Value: No module named http_client

当我进入 django shell 时，我可以毫无问题地执行以下导入 from django.utils.six.moves import http_client。此外，在我导入 http_client 之后，我还执行了一个 dir(http_client) 并且我可以看到响应对象，但是由于某种原因，当我尝试使用 from django.utils.six.moves.http_client import responses 导入时，我得到一个 ImportError: No module名为 http_client。这至少可以说是非常令人沮丧的。

看起来您正在点击 issue 2969 .如果您从 Django 1.6 升级到 1.6.11，它应该可以工作。但是，请注意 1.6 现已停产并且不会收到安全修复程序，因此理想情况下您应该升级到最新的受支持 Django 版本或最新的 LTS。
