Problem mit der Installation von Symfony Doktrin-Migrationen-Bundle

Während ich den Befehl php composer.phar update ausführen zeigt es den folgenden Fehler. Kann mir jemand helfen, um es zu reparieren?

Entfernen Sie zuerst das Bündel aus Ihrem composer.json.

Dann versuchen:

// replace app by var depending on your symfony version (2 or 3) 
rm -Rf app/cache 
// clean all your dependencies 
rm -Rf vendor 
// reinstall them from your composer.lock 
composer install 
// install this particular bundle 
composer require doctrine/doctrine-migrations-bundle "^1.0"
