django - 无法在 Heroku 上配置 MemCached

Question

我正在尝试使用 heroku 附加组件' MemCacheCloud 配置 MemCached ' 用于我的 Django 网站。当我运行试图获取/设置缓存的代码时，出现以下错误

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

我在dataaccess.py中访问缓存的代码-

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 有一个条目

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')
            }
      }
}

当我评论 dataaccess.py 中的 cache.set 和 cache.get 行时，代码运行完美。
