symfony 2.0中的学说问题

我正在尝试运行：

php app/console doctrine:fixtures:load

但我经常收到这样的错误：

Fatal error: Class 'Symfony'Bundle'DoctrineFixturesBundle' not found in /Library/WebServer/Documents/Symfony/app/AppKernel.php on line 17

这是我的AppKernel.php：

<?php
use Symfony'Component'HttpKernel'Kernel;
use Symfony'Component'Config'Loader'LoaderInterface;
class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            new Symfony'Bundle'FrameworkBundle'FrameworkBundle(),
            new Symfony'Bundle'SecurityBundle'SecurityBundle(),
            new Symfony'Bundle'TwigBundle'TwigBundle(),
            new Symfony'Bundle'MonologBundle'MonologBundle(),
            new Symfony'Bundle'SwiftmailerBundle'SwiftmailerBundle(),
            new Symfony'Bundle'DoctrineBundle'DoctrineBundle(),
            new Symfony'Bundle'DoctrineFixturesBundle(),
            new Symfony'Bundle'AsseticBundle'AsseticBundle(),
            new Sensio'Bundle'FrameworkExtraBundle'SensioFrameworkExtraBundle(),
            new JMS'SecurityExtraBundle'JMSSecurityExtraBundle(),
            new Acme'HelloBundle'AcmeHelloBundle(),
            new Blogger'BlogBundle'BloggerBlogBundle(),
        );
        if (in_array($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');
    }
}

这是我的代表文件中与条令有关的一部分：

[doctrine-common]
    git=http://github.com/doctrine/common.git
    version=2.2.0
[doctrine-dbal]
    git=http://github.com/doctrine/dbal.git
    version=2.2.1
[doctrine]
    git=http://github.com/doctrine/doctrine2.git
    version=2.2.0
[doctrine-fixtures]
    git=http://github.com/doctrine/data-fixtures.git
[DoctrineFixturesBundle]
    git=http://github.com/doctrine/DoctrineFixturesBundle.git
    target=bundles/Doctrine/Bundle/FixturesBundle
