PHP7: problème d'installation d'ext-dom

J'utilise laravel 5.4 sur le serveur Ubuntu 16.04 avec PHP7. essayer d'installer le paquet cviebrock/eloquent-sluggable lance une erreur:

pish@let:/home/sherk/ftp/www$ Sudo composer require cviebrock/eloquent-sluggable
Do not run Composer as root/super user! See https://getcomposer.org/root for details

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - phpunit/php-code-coverage 4.0.7 requires ext-dom * -> the requested PHP extension dom is missing from your system.
    - phpunit/php-code-coverage 4.0.7 requires ext-dom * -> the requested PHP extension dom is missing from your system.

  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

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

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

Tout d'abord, lisez l'avertissement! Il dit do not exécutez composer comme racine! Deuxièmement, vous utilisez probablement Xammp sur votre réseau local qui a les bibliothèques php requises par défaut.

Mais dans votre serveur, il vous manque ext-dom. php7.1-xml contient tous les packages connexes dont vous avez besoin. Donc, vous pouvez simplement l'installer en lançant:

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

Il est fort probable que vous manquiez également mbstring. Si vous obtenez l'erreur, installez également ce paquet avec:

Sudo apt-get install php-mbstring

Puis lancez:

composer update
composer require cviebrock/eloquent-sluggable

Pour ceux qui veulent installer ext-dom sur php 7.1 et supérieur, exécutez cette commande:

Sudo apt install php-xml
