缺少 PHP DOM 文件

Question

我在运行 $dom = new DOMDocument("1.0", "utf-8") 时遇到一个奇怪的错误；:警告:require_once(classes/DOMDocument.class.php) [function.require-once]:无法打开流:/var/www/html/cms/中没有这样的文件或目录bootstrap.php 在 5
行
fatal error :require_once() [function.require]:无法打开所需的'classes/DOMDocument.class.php' (include_path='.:/usr/share/pear:/usr/share/php :/var/www/html/cms/plugins/Zend/library') 在 /var/www/html/cms/bootstrap.php 上 5

根据 php.net/manual/en/dom.setup.php，我需要安装 php-xml。我已经试过了，但它也出错了......

 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.

Package matching php-common-5.1.6-27.el5_5.3.i386 already installed. Checking for update.
