無法在Heroku上配置MemCached

我想爲我的Django網站使用heroku插件'MemCacheCloud'來配置MemCached。當我運行正試圖獲取代碼/設置緩存，然後我收到以下錯誤無法在Heroku上配置MemCached

Mar 31 19:36:17 mycloudapp app/web.1: error: [Errno 9] Bad file descriptor

我的代碼來訪問緩存dataaccess.py -

from django.core.cache import cache 

ALL_SKILLS = "allskills" 
def get_all_skills(): 
    skill_list = cache.get(ALL_SKILLS) 
    if not skill_list: 
     skill_list = MySkillTable.objects.all() 
     cache.set(ALL_SKILLS, skill_list) 
    return skill_list

我的settings.py有入口

CACHES = { 
     'default': { 
     'BACKEND': 'django_bmemcached.memcached.BMemcached', 
     'LOCATION': get_env_setting('MEMCACHEDCLOUD_SERVERS').split(','), 
     'OPTIONS': { 
        'username': get_env_setting('MEMCACHEDCLOUD_USERNAME'), 
        'password': get_env_setting('MEMCACHEDCLOUD_PASSWORD') 
      } 
     } 
}

當我在評論dataaccess.py cache.set & cache.get線，代碼完美的作品。

獲取相同的東西。你找到解決方法嗎？ – johnboiles

@johnboiles - 我通過電子郵件發送了同樣的支持，得到了回覆，看到我的堆棧跟蹤後，他們在'bmemcached'中發現了一些錯誤。他們修復了錯誤並將修補程序提交給了'bmemcached'，但現在由bmemcached團隊發佈新版本。他們告訴我使用[pylibmc]（https://github.com/lericson/pylibmc）的解決方法。我沒有嘗試過，因爲現在我使用的是不同的附加組件，例如[redis雲]（https://addons.heroku.com/marketplace/rediscloud） – anuragal

@anuragal您應該回答自己的問題。如果您知道他們記錄了哪個[問題]（https://github.com/jaysonsantos/python-binary-memcached/issues），則可以將其鏈接。 –

感謝@ChrisWesseling的建議。

根據來自支持的通信，issue#25針對上述問題開放。現在它已被修復，並且根據它們，pip存儲庫也隨此修復程序一起更新。
