[3.x] Problème 1 au lancement de update

Bonjour tout le monde,

J'utilise Sonata Admin Bundle et je suis à l'étape d'installation de User Bundle. Je lance les commandes suivantes :
Code:

1 2 3 4 5 php composer.phar require sonata-project/user-bundle --no-update php composer.phar require sonata-project/doctrine-orm-admin-bundle --no-update php composer.phar require friendsofsymfony/rest-bundle --no-update php composer.phar require nelmio/api-doc-bundle --no-update php composer.phar update
Au lancement de la dernière commande (update), j'ai ça comme erreur :
