Memcache状态不适用于Django 1.11和Python 3.6

Question

我为我的django项目（Django 1.11和Python 3.6）安装了memcached。 当我在settings.py的memcached_status添加到我安装的应用程序，我得到这个错误，当我尝试打开Django管理页面：

在他们的github回购他们说，我只需要memchache_status增加我在settings.py中安装的应用程序，它会工作。 有没有人有同样的问题？如果是，我应该如何正确安装我的Django管理页面的memchached状态。

更新

我怀疑你也安装python3-memcached（现在已废弃，请参见README）可能已经覆盖您的python-memcached安装（现在支持Python 2 & 3）在这种情况下。如果是这样，您需要删除python3-memcached和python-memcached，然后重新安装后者，版本> = 1.58。

您需要将python-memcache升级到最新版本，当前是1.58。

该包与您的memcached服务器进行交互，以提取其收集的统计信息。早期版本的软件包没有将传入的统计数据（特别是密钥）解码为Python 3 str类型（即unicode），并且仅将bytes字符串传递给memcached_statusprettyname过滤器 - 该过滤器假定str对象。
