I installed wamp server and a copy of the Symfony2 framework. I am trying to create a Bundle, using the following command:
php app/console generate:bundle --nam
To execute command you should move to root directory of your project in terminal/CMD.
Please note that in version 2.5 some changes has been made so command will not work with app/console
Note: From 2.5 app/console is replaced by bin/console.
Please check here for changes. Also check this for more details about difference.
