【问题描述】：

我正在尝试在新创建的 Amazon EC2 实例上安装 php-dom 扩展，但没有成功，但无论我尝试什么...

我尝试了以下命令（以及其他一些命令）：

sudo yum install php-dom

sudo yum install php-xml

这是我每次得到的：

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

据我了解，php-xml（包括 php-dom）需要包 php-common 版本 5.4.16（？！），但我正在运行 PHP 版本 7.3，这可能是导致冲突？

我对 AWS 还很陌生，甚至更多关于终端命令，所以这里的任何帮助都非常感谢！如果您需要有关服务器的更多信息，我很乐意提供给您，我只是不知道那时有什么用处......

谢谢。

你检查过哪些模块已经安装了吗？

如果您使用 php 7.3 安装

sudo amazon-linux-extras install php7.3

那么使用sudo yum install php-xml 为7.3 安装php-xml 应该没有任何问题：
