Root Cause

Memcached Python client library is not installed.

generic

中文

未安装 Memcached Python 客户端库。

Workarounds

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

Dead Ends

Common approaches that don't work:

  1. 50% fail

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

  2. 70% fail

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