参考一下这个: http://douban-code.github.io/pages/python-libmemcached.html

[lidashuang]

@xtao 试过，用的第一个方法装的，这个要在virtualenv的环境下装吗？

[Xu Tao]

@lidashuang 那你的memcached的版本是多少？

[lidashuang]

@xtao memcached 1.4.13 on ubuntu 12.04 64 位

@lidashuang 你安装libmemcached有问题 请参考我的issue #16

[lidashuang]

ubuntu 12.04 有这问题，拷了个（ubuntu 13.04）的cmemcached_imp.so就可以了
