Memcache no servidor ubuntu lúcido e rubi 1.9.1

Question

Estou tentando configurar um servidor memcache na configuração acima. Estou recebendo o seguinte erro:

Mas o memcache-client 1.8.3 está na lista gem. Qual é o problema?

    

Answer 1

No que diz respeito ao memcached, posso ajudar:

telnet localhost 11211
stats
quit

( quit ou exit eu sempre esqueço isso.)

Se isso não funcionar - é claro, substitua localhost pelo seu servidor de memcached real - no Ubuntu e no Debian, o simples apt-get install memached irá disponibilizá-lo. Desde que eu tenho absolutamente nenhuma idéia o que esta mensagem ruby significa que é apenas um palpite.

Além disso, tirei a liberdade da questão para que ela mencionasse o material do rubi.
