php - AppKernel.php 第 25 行 : 中的 ClassNotFoundException

Question

您好，当我尝试加载我的 symfony 2 应用程序时出现此问题，

ClassNotFoundException in AppKernel.php line 25: Attempted to load class "SonataDoctrineORMAdminBundle" from namespace "Sonata\DoctrineORMAdminBundle". Did you forget a "use" statement for another namespace?

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，但由于这个问题也无法更新

要事第一。您确定您的composer.json 文件包含以下标记为<== 重要:
