PHP7 : install ext-dom issue

Question

I\'m running laravel 5.4 on Ubuntu 16.04 server with PHP7. trying to install cviebrock/eloquent-sluggable package throw some error:

pish@let:/ho         


        

Answer 1

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 update
sudo apt install php-xml

Most likely you are missing mbstring too. If you get the error, install this package as well with:

sudo apt-get install php-mbstring

Then run:

composer update
composer require cviebrock/eloquent-sluggable
