PHP7 : install ext-dom issue
First of all, read the warning! It says do not run composer as root! Secondly, you're probably using Xammp on your local which has the required php libraries as default.
But in your server you're missing ext-dom. php-xml has all the related packages you need. So, you can simply install it by running:
sudo apt-get updatesudo apt install php-xmlMost likely you are missing mbstring too. If you get the error, install this package as well with:
sudo apt-get install php-mbstringThen run:
composer updatecomposer require cviebrock/eloquent-sluggable
For whom want to install ext-dom on php 7.1 and up run this command:
sudo apt install php-xml
sudo apt install php-xml will work but the thing is it will download the plugin for the latest PHP version.
If your PHP version is not the latest, then you can add version in it:
# PHP 7.1sudo apt install php7.1-xml# PHP 7.2:sudo apt install php7.2-xml# PHP 7.3sudo apt install php7.3-xml# PHP 7.4sudo apt install php7.4-xml# PHP 8sudo apt install php-xml
