Must define a 'defaut' cache in your CACHE setting.

[Iazzetta]

When I try this:

CACHES = {
    'django_cache_manager.cache_backend': {
        'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
        'LOCATION': '127.0.0.1:11211',
    }
}

I get this:

(caches.E001) You must define a 'default' cache in your CACHES setting.

You need to define a default cache in your django project settings in addition to the above the namespace.
