我使用说明在 Django 1.6 中安装了 johnny-cache 1.4 但不起作用：

# add johnny's middleware
MIDDLEWARE_CLASSES = (
    'johnny.middleware.LocalStoreClearMiddleware',
    'johnny.middleware.QueryCacheMiddleware',
    # ...
)
# some johnny settings
CACHES = {
    'default' : dict(
        BACKEND = 'johnny.backends.memcached.MemcachedCache',
        LOCATION = ['127.0.0.1:11211'],
        JOHNNY_CACHE = True,
    )
}
JOHNNY_MIDDLEWARE_KEY_PREFIX='jc_myproj'

出现的错误是：

$ python manage.py runserver

调查并说问题更多是 Django，我想修复它，因为这是一个很棒的工具，它会很有帮助。

升级到今天更新的 Django 版本 1.7，继续同样的问题，我所做的是升级到版本 johnny 缓存开发：

johnny-cache==1.6.1a
python-memcached==1.53

有了这个我暂时解决了问题，直到他们更新
