【问题描述】：

我正在尝试使用 yum 在Centos 6.4 中安装php54-xml。

我在控制台中执行了yum install php54-xml，但出现以下错误：

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

我尝试安装php-cli 来解决问题，然后我收到以下错误：

似乎php5.3.x 之间存在冲突，这是我在php5.4.x 看到的以前的版本

有没有办法安装php54-xml，这样我就可以使用dom_import_simplexml 函数，因为我在控制台中运行PHP 脚本时遇到undefined 错误？

【问题讨论】：

您需要选择 5.3 或 5.4，因为无法同时安装这两个版本：它们共享共同文件，这会产生您在终端上看到的冲突。
@SamiLaine 如何删除 Php 5.3？
您似乎已经从存储库 php-ius 安装了一些 PHP 包（甚至可能是 PHP 本身）。该存储库是否默认启用（请参阅/etc/yum.repos.d 中的文件，它们只是文本文件并且易于解释）？如果没有，请尝试使用--enable-repo='*ius*' 运行yum install，看看是否有更少/更多的冲突。

【解决方案1】：

除了普通的 CentOS 存储库之外，您还有一堆来自一堆存储库（php-ius、webtatic）的软件包。这些 repos 中的包可能有不同的方式将其包集成到系统中。我建议坚持一个来源 - 例如Red Hat 支持的 Software Collections 存储库 - 从那里安装的软件包可以并存，即您可以并行安装多个 PHP 版本：

要在从 Software Collections 安装软件包之前清理您的系统，我建议删除所有第 3 方软件包。您可以通过以下方式显示要删除的包：

yum list extras --disablerepo=\* --enablerepo=base --enablerepo=updates
yum remove <all_the_listed_packages>

第一个命令基本上列出了您从存储库安装的所有软件包，而不是 CentOS 的 base 或 updates 存储库。
