我已经成功安装了 memcached，并且似乎运行正常，现在我需要安装 PECL 扩展 memcache。我正在运行 Centos 6.2 x86_64。当我尝试安装时，底部出现此错误：

=========================================
Package Version State
APC 3.1.13 beta
memcache 3.0.8 beta
我真的很感激一些解决这个问题的建议，谢谢
yum groupinstall 'Development Tools'并且yum install zlib-devel已经安装
我尝试运行yum install memcached-beta --disable-memcached-sasl，yum install memcached-beta --enable-memcached-sasl=no
但结果相同
答案1
Memcached >2.1 至少需要 libmemcached 1.x。您似乎仍安装有 0.31。
删除当前的 libmemcached 包并安装 libmemcached10（加上 -devel）。
这些包至少可以在 IUS 存储库中找到。
