嘗試為 php 安裝 apc 擴展時缺少依賴項問題

我正在嘗試根據本教程為 php 安裝 apc 擴展：http: //2bits.com/articles/installing-php-apc-gnulinux-centos-5.html但無法成功執行第一個命令。這是我得到的：

You could try using --skip-broken to work around the problem
You could try running: package-cleanup --problems
                       package-cleanup --dupes
                       rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.

有誰知道這兩個錯誤是什麼意思，我應該如何解決？

我認為這就是我無法在我的伺服器上安裝 apc 的原因。伺服器執行 centos 5.6，php 5.3.8。控制面板是 plesk 10。

你是如何安裝 php-5.3.8 的？php-devel 包的版本必須與您安裝的 php 匹配。先安裝對應的php-devel，再安裝php-pear再試。不過，我不知道該軟體包是否會尋找特定版本的 php。如果是這樣，您需要找到適合版本的 php-pear 包。
