Votre message d'erreur est assez explicite sur ce qui ne va pas:
laravel/framework v5.2.9 requiert ext-mbstring * -> l'extension PHP demandée mbstring est absente de votre système.
Avez-vous mbstring
installé sur votre serveur et est-il activé?
Vous pouvez installer mbstring
dans le cadre du paquet libapache2-mod-php5:
Sudo apt-get install libapache2-mod-php5
Ou autonome avec:
Sudo apt-get install php-mbstring
L'installer le permettra également, mais vous pouvez aussi l'activer en modifiant votre fichier php.ini
et en supprimant le ;
qui le commente s'il est déjà installé.
Si cela se trouve sur votre ordinateur local, suivez les étapes appropriées pour l'installer sur votre environnement.
pour php7 vous pouvez faire ça:
Sudo apt-get install php-Gd php-xml php7.0-mbstring
Dans php7.2 Ubuntu 18.04 LTS
Sudo apt-get install php-Gd php-xml php7.2-mbstring
Fonctionne comme un charme
Après avoir installé les paquets à partir des réponses données, il y a toujours des erreurs, puis j'installe le paquet suivant et ça marche très bien:
pour version spécifique:
commande pour php 7.0
Sudo apt-get install php7.0-xml
dans certains cas, vous avez également besoin d'un paquet php7.0-common. installez le même que la commande ci-dessus.
Beaucoup de bonnes réponses déjà pour Ubuntu. Je suis sur Linux et ai le même problème, mais aucune des commandes ci-dessus ne fonctionnait pour moi.
Avec Linux et php70, j'ai utilisé la commande suivante qui fonctionnait très bien:
Sudo yum install php70-mbstring -y
Si vous utilisez php 7.3 pour laravel 5.7. ce travail pour moi
Sudo apt-get install php-Gd php-xml php7.3-mbstring
