FOSUserBundle not found in appkernel

Question

I am using symfony on Windows and I tried to configure FOSUserBundle as described in the official documentation.

I get this error when try to update the schema:

Class 'FOS\UserBundle\FOSUserBundle' not found in app/AppKernel.php line 20;

searched for the problem and find this solution: adding this to autoload.php

$loader->registerNamespaces(array(
    //all the rest
    'FOS' => $vendor_dir . '/bundles',
));

but it returns another error which says

call to undefined method ...\ClassLoader::RegisterNamespace() in ...\autoload.php on line 13

can anybody plz tell me what should i do?:|

and this is my appkernel.php file:

<?php

use Symfony\Component\HttpKernel\Kernel;
use Symfony\Component\Config\Loader\LoaderInterface;

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
            new Symfony\Bundle\SecurityBundle\SecurityBundle(),
            new Symfony\Bundle\TwigBundle\TwigBundle(),
            new Symfony\Bundle\MonologBundle\MonologBundle(),
            new Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle(),
            new Symfony\Bundle\AsseticBundle\AsseticBundle(),
            new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
            new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
            new Sad\Bundle\WarehouseBundle\SadWarehouseBundle(),
            new FOS\UserBundle\FOSUserBundle(),
        );

       if (in_array($this->getEnvironment(), array('dev', 'test'))) {
            $bundles[] = new Acme\DemoBundle\AcmeDemoBundle();
            $bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
            $bundles[] = new Sensio\Bundle\DistributionBundle\SensioDistributionBundle();
            $bundles[] = new Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle();
        }

        return $bundles;
    }

    public function registerContainerConfiguration(LoaderInterface $loader)
    {
        $loader->load(__DIR__.'/config/config_'.$this->getEnvironment().'.yml');
    }
}

I had the same problem. I found out that the FOSUserBundle was not properly installed. You should delete your /vendor/friendsofsymfony/ directory and then update the bundle using:

php composer.phar update friendsofsymfony/user-bundle

It worked for me. I hope it helps someone else having the same issue.
