PHP7: installe le problème d’ext-dom

J’exécute laravel 5.4 sur le serveur Ubuntu 16.04 avec PHP7. essayant d’installer le cviebrock/eloquent-sluggable jette une erreur:

 pish@let:/home/sherk/ftp/www$ sudo composer require cviebrock/eloquent-sluggable Do not run Composer as root/super user!

Installation failed, reverting ./composer.json to its original content. 

Je n’ai aucun problème à installer ce package sur la version locale de l’application.

    Tout d’abord, lisez l’avertissement! Il dit ne pas exécuter compositeur en tant que root ! Deuxièmement, vous utilisez probablement Xammp sur votre version locale qui a les bibliothèques PHP requirejses par défaut.

    Mais dans votre serveur, il vous manque ext-dom . php7.1-xml a tous les paquets nécessaires dont vous avez besoin. Donc, vous pouvez simplement l’installer en exécutant:

     sudo apt-get update sudo apt-get install php7.1-xml 

    Vous avez probablement aussi mbssortingng . Si vous obtenez l’erreur, installez également ce package avec:

     sudo apt-get install php-mbssortingng 

    Puis lancez:

     composer update composer require cviebrock/eloquent-sluggable 

    Pour ceux qui veulent installer ext-dom sur php 7.2, exécutez cette commande:

     sudo apt install php-xml
