What is happening here ?

Answer 1

Do you have this line in your composer.json ?

"sensio/generator-bundle": "2.3.*"

And this one is your AppKernel.php (in the dev, test section) ?

new Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle();

Answer 2

你应该先做composer require sensio/generator-bundle 。
