PHP Erreur irrécupérable: Uncaught Erreur: Classe 'DOMDocument' introuvable sur Symfony

Question

J'ai vérifié toutes les questions liées, mais les solutions n'ont pas résolu le problème que je reçois.

Je suis en train de définir une instance EC2, l'installation php7.0, mysql, compositeur, cloné le dépôt, etc ..

Cette instance EC2 est un Centos 6.5.

Mais quand:

php bin/console cache:clear --env=prod --no-debug 

Je reçois:

PHP Fatal error: Uncaught Error: Class 'DOMDocument' not found in /var/www/html/TFM_RedSocialMusical/vendor/symfony/symfony/src/Symfony/Component/Config/Util/XmlUtils.php:52

Eh bien, à la recherche des questions similaires, la solution est purposed:

sudo yum install php-xml

You could try using --skip-broken to work around the problem 
You could try running: rpm -Va --nofiles --nodigest 

J'ai installé le php70u-common, mais comment éviter ce conflit avec php-common-5.3.3-49?

Merci à l'avance

Answer 1

Comme dit sur les commentaires, l'installation php70u-xml a résolu le problème.
