Я потратил много времени на это, и это явно выходит за рамки моего понимания / навыков новичка. Я пытался установитьДжанго-Heroku-memcacheify с установкой pip, которая выдает ошибки. Я отследил проблему доpylibmc, что вызывает все проблемы. Вот одна из интересных частей журнала ошибок:

_pylibmcmodule.h:42:36: error: libmemcached/memcached.h: No such file or directory

here's the (almost) complete traceback:

So here's the deal

Я не могу проверить это в моем локальном окружении, которое я запускаю на куске Windows. Но из того, что я прочиталlibmemcached являетсяуже установлено на героку. И, похоже, ни у кого больше нет проблем с pylibmc, потому что я ничего не могу найти в Google.В этом посте они говорят о:

that if they detect that you are loading pylibmc, they will bootstrap libmemcached for you

Это может быть проблемой, либо она не указана, либо указан неверный путь. Любая помощь приветствуется! если это не сработает, мне придется использовать Redis, который кажется намного сложнее ... не знаю, достаточно ли я продвинут для этого.

Edit Возможно, это не имеет значения, но я использую папку настроек с init вместо файла settings.py. Я слышал, что это может привести к странному поведению, поскольку heroku не всегда помнит, что это возможно.

Edit 2

Поскольку сотни людей без проблем запускают memcached и django на heroku, я не думаю, что пользователи heroku должны устанавливать libmemcached с каким-то хаком. Документы говорят об этом, как будто он загружается для вас, когда heroku обнаруживает pylibmc в вашем файле требований. Что приводит меня к выводу:A) либо что-то не так в моих настройках или в одном из приложений, которые я использую, илиB) heroku недавно что-то изменил и сломал автоматическую загрузку libmemcached для django. Я пытался получить новую установку с помощью конфигурации heroku: добавьте CLEAN_VIRTUALENV = true, нокоторый сейчас тоже не работает, Я надеюсь, что этоA и у кого-то была такая же проблема. Если этоB Понятия не имею, как это решить.
