Question

我想在我的Django 1.11项目中使用Memcached。我使用的是Python 3.6。我已经在我的mac OSX终端上用Homebrew安装了memcached。之后我安装了它的python绑定：

pip install python-memchached==1.58

然后我将必要的配置添加到我的settings.py项目文件中：

 CACHES = {
  'default': {
     'BACKEND':'django.core.cache.backends.memcached.MemcachedCache',
     'LOCATION':'127.0.0.1:11211',
  }
}

我有两个终端，一个用于我的本地主机，另一个用于memcached：

memcached -l 127.0.0.1:11211

当我刷新我的网页时，我收到以下错误：

有人能指出我解决问题的方法吗？

无法在Django 1.11中使用Memcached（无法导入名称'get_cache'）
