Laravel 4 generate not working :: solved

 [InvalidArgumentException]

 There are no commands defined in the "generate" namespace.

solved by the below method :) 

Begin by installing this package through Composer. Edit your project's composer.json file to require way/generators.

"require-dev": {
    "way/generators": "~2.0"
}

Next, update Composer from the Terminal:

composer update --dev

Once this operation completes, the final step is to add the service provider. Openapp/config/app.php, and add a new item to the providers array.

'Way\Generators\GeneratorsServiceProvider'\
