在 Amazon EC2 上安裝 php-dom 擴展

Question

我正在嘗試在新創建的 Amazon EC2 實例上安裝 php-dom 擴展失敗，但無論我怎么嘗試都失敗了...

我嘗試了以下命令（以及其他命令）：

sudo yum install php-dom

sudo yum install php-xml

這是我每次得到的：

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

據我了解，php-xml（包括 php-dom）需要 php-common 版本 5.4.16（？！），但我運行的是 PHP 7.3 版，這可能是沖突的原因？

我對 AWS 還很陌生，甚至更多地了解終端命令，因此非常感謝這里的任何幫助！ 如果您需要有關服務器的更多信息，我很樂意為您提供，我只是不知道那時有什么用...

謝謝你。

如果您使用安裝了 php 7.3

sudo amazon-linux-extras install php7.3

那么使用sudo yum install php-xml為 7.3 安裝php-xml應該沒有任何問題：
