上記の設定で memcache サーバーを設定しようとしています。次のエラーが発生します:

しかし、memcache-client 1.8.3 は gem リストにあります。何が問題なのでしょうか?
答え1
memcached に関しては、私がお手伝いできることは次のとおりです:
telnet localhost 11211
stats
quit
（quit または exitいつもそれを忘れてしまいます。
それでもうまくいかない場合は、もちろんlocalhost実際のmemcachedサーバーに置き換えてください。UbuntuとDebianでは、apt-get install memached方法で利用できます。全く分かりませんこのルビーメッセージが何を意味するのか、これは単なる推測です。
また、私は Ruby に関する内容が記述されるように、質問を自由にしました。
