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：第5行的/var/www/html/cms/bootstrap.php中没有这样的文件或目录

致命错误：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第5行的/var/www/html/cms/bootstrap.php中的/ cms / plugins / Zend / library’)

根据php.net/manual/en/dom.setup.php,我需要安装php-xml.我试过这个,但它也错了…

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.

Nothing to do
