AppKernel.php中的ClassNotFoundException第25行:

嗨，当我试图加载我的symfony 2应用程序时，出现了这个问题，

AppKernel.php第25行中的ClassNotFoundException：试图从命名空间"Sonata''DoctrineORMAdminBundle"加载类"SonataDoctrineORMAdminBundle"。您是否忘记了另一个命名空间的"use"语句？

这是我的AppKernel.php文件，

    <?php
use Symfony'Component'HttpKernel'Kernel;
use Symfony'Component'Config'Loader'LoaderInterface;
class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            new Symfony'Bundle'FrameworkBundle'FrameworkBundle(),
            new Symfony'Bundle'SecurityBundle'SecurityBundle(),
            new Symfony'Bundle'TwigBundle'TwigBundle(),
            new Symfony'Bundle'MonologBundle'MonologBundle(),
            new Symfony'Bundle'SwiftmailerBundle'SwiftmailerBundle(),
            new Symfony'Bundle'AsseticBundle'AsseticBundle(),
            new Doctrine'Bundle'DoctrineBundle'DoctrineBundle(),
            new Sensio'Bundle'FrameworkExtraBundle'SensioFrameworkExtraBundle(),
            new AppBundle'AppBundle(),
            new kcc'AdminBundle'kccAdminBundle(),
            new JMS'SerializerBundle'JMSSerializerBundle(),
            new Sonata'CoreBundle'SonataCoreBundle(),
            new Sonata'BlockBundle'SonataBlockBundle(),
            new Knp'Bundle'MenuBundle'KnpMenuBundle(),
            new Sonata'DoctrineORMAdminBundle'SonataDoctrineORMAdminBundle(),
            new Sonata'AdminBundle'SonataAdminBundle(),
        );
        if (in_array($this->getEnvironment(), array('dev', 'test'), true)) {
            $bundles[] = new Symfony'Bundle'DebugBundle'DebugBundle();
            $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)
    {
        $loader->load($this->getRootDir().'/config/config_'.$this->getEnvironment().'.yml');
    }
}

我也尝试更新composer，但由于这个问题，它也无法更新
