===

I am following the tutorial

    [http://www.ens.ro/2012/03/27/symfony2-jobeet-day-3-the-data-model/][1]

when i am using the command

    php app/console doctrine:fixtures:load
then i am getting an error

    C:\wamp\www\Symfony>php app/console doctrine:fixtures:load
    'stty' is not recognized as an internal or external command,
    operable program or batch file.
    
    
    
    
    
    
    
      [RuntimeException]
    
    
    
    
      The autoloader expected class "Symfony\Bundle\DoctrineFixturesBundle\DoctrineF
    ixturesBundle" to be defined in file "C:\wamp\www\Symfony\app/../vendor/bundles\
    Symfony\Bundle\DoctrineFixturesBundle\DoctrineFixturesBundle.php". The file was
    found but the class was not in it, the class name or namespace probably has a ty
    po.

I am new to symfony2. please help me
