Memcached Python client library is not installed.

generic

解决方案

  1. 90% 成功率 
    pip install python-memcached
  2. 80% 成功率 
    Use django.core.cache.backends.locmem.LocMemCache for development instead.

无效尝试

常见但无效的做法:

  1. 50% 失败

    Changing CACHE_BACKEND to locmem without installing memcached doesn't solve if you need memcached.

  2. 70% 失败

    Installing wrong package (e.g., memcache vs python-memcached) can cause import errors.
