First of all, read the warning! It says do notrun composer as root! Secondly, you're probably using Xammp on your local which has the required php libraries as default.
首先，请阅读警告！它说，你不跑作曲家根！其次，您可能在本地使用 Xammp，它默认具有所需的 php 库。
But in your server you're missing ext-dom. php-xmlhas all the related packages you need. So, you can simply install it by running:
但是在您的服务器中，您缺少ext-dom. php-xml拥有您需要的所有相关软件包。因此，您可以通过运行简单地安装它：
sudo apt-get update
sudo apt install php-xml
Most likely you are missing mbstringtoo. If you get the error, install this package as well with:
很可能你也失踪mbstring了。如果出现错误，请使用以下命令安装此软件包：
sudo apt-get install php-mbstring
Then run:
然后运行：
composer update
composer require cviebrock/eloquent-sluggable
