我在这上面花了很多时间，这显然超出了我的新手理解/技能。我试图安装django-heroku-memcacheify pip安装，它会引发错误。我将问题追踪至pylibmc，这是造成所有问题的原因。下面是错误日志的有趣的部分之一：Heroku上的Memcached w/Django：无法安装pylibmc/memcacheify
_pylibmcmodule.h：42：36：错误：libmemcached/memcached.h：没有这样的文件或目录

所以这里的交易
我不能TES在我的本地环境中，我正在运行一个窗口的废话。但从我读的libmemcached是already installed在heroku上。而且没有其他人似乎对pylibmc有任何问题，因为我在谷歌上找不到任何东西。 In this post他们谈论：
that if they detect that you are loading pylibmc, they will bootstrap libmemcached for you
这可能是问题，要么它不提供或路径是错误的。任何帮助表示赞赏！如果这不起作用，我将不得不使用Redis，这似乎更难了...不知道我是否足够先进。
编辑 可能是无关紧要的，但我使用一个设置使用init而不是settings.py文件夹中。我听说这可能会导致一些奇怪的行为，因为heroku并不总是记得这是可能的。
编辑2
既然有数百人捉迷藏Memcached和在Heroku Django的没有任何问题，我不认为Heroku的用户都应该安装libmemcached带有某种黑客。当heroku在您的需求文件中检测到pylibmc时，文档会对它进行讨论，好像它是为您启动的。这导致我得出结论：A）无论是在我的设置或我使用的应用程序中的一个错误或B） heroku最近改变了一些东西，并打破了django libmemcached的自动引导。我试着用heroku config进行全新安装：添加CLEAN_VIRTUALENV = true，但是that's not working either right now。我希望这是A和有人有同样的问题。如果它是B我不知道如何解决它。
这个问题刚刚开始发生在我身上了今天的蓝...和memcached的已经工作了几个月对我来说。我很高兴你问这个，因为tiwei的答案是现货。我已将我的需求重新组织为多个需求文件，并根据需求导入它们;这似乎是致命的。我想我只是把pylibmc放在根文件中，并且应该清除它。 – 2013-01-03 23:27:12
