symfony2：找不到AppKernel中包含的类

我有这个app/AppKernel:

<?php

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

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
            new Symfony\Bundle\SecurityBundle\SecurityBundle(),
            new Symfony\Bundle\TwigBundle\TwigBundle(),
            new Symfony\Bundle\MonologBundle\MonologBundle(),
            new Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle(),
            new Symfony\Bundle\AsseticBundle\AsseticBundle(),
            new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
            new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
            new JMS\AopBundle\JMSAopBundle(),
            new JMS\DiExtraBundle\JMSDiExtraBundle($this),
            new JMS\SecurityExtraBundle\JMSSecurityExtraBundle(),
            new JMS\I18nRoutingBundle\JMSI18nRoutingBundle(),
            new FOS\UserBundle\FOSUserBundle(),
            new Sports\FrontendBundle\SportsFrontendBundle(),   // line 25             
            new Sports\UserBundle\SportsUserBundle(),
            new Sonata\DefaultBundle\SonataDefaultBundle(),
            new Sonata\DoctrineORMAdminBundle\SonataDoctrineORMAdminBundle(),
            new Sonata\AdminBundle\SonataAdminBundle(),
            new Sonata\BlockBundle\SonataBlockBundle(),
            new Sonata\CacheBundle\SonataCacheBundle(),
            new Knp\Bundle\MenuBundle\KnpMenuBundle(),
            new Stof\DoctrineExtensionsBundle\StofDoctrineExtensionsBundle()
        );

        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');
    }

还有这堂课src/Sports/FrontendBundle/SportsFrontendBundle.php:

namespace Sports\FrontendBundle;

use Symfony\Component\HttpKernel\Bundle\Bundle;

class SportsFrontendBundle extends Bundle
{
}

我收到此错误：

致命错误：类“Sports\FrontendBundle\SportsFrontendBundle”不是 位于 /home/tirengarfio/programacion/sports/app/AppKernel.php 上 25号线

这是我的app/autoload.php:

<?php

use Doctrine\Common\Annotations\AnnotationRegistry;

if (!$loader = @include __DIR__.'/../vendor/autoload.php') {

    $message = <<< EOF
<p>You must set up the project dependencies by running the following commands:</p>
<pre>
    curl -s http://getcomposer.org/installer | php
    php composer.phar install
</pre>

EOF;

    if (PHP_SAPI === 'cli') {
        $message = strip_tags($message);
    }

    die($message);
}

// intl
if (!function_exists('intl_get_error_code')) {
    require_once __DIR__.'/../vendor/symfony/symfony/src/Symfony/Component/Locale/Resources/stubs/functions.php';

    $loader->add('', __DIR__.'/../vendor/symfony/symfony/src/Symfony/Component/Locale/Resources/stubs');
    $loader->add('Sports',   __DIR__ . '/../src');
}

AnnotationRegistry::registerLoader(array($loader, 'loadClass'));

return $loader;

and my composer.json:

任何想法？

为了将来的参考，如果您签出代码并直接复制供应商文件夹而不运行 Composer，则可能会发生类似的问题。

要排除自动加载问题，您只需运行install在你的 symfony2 文件夹中（假设你有composer.phar那里 ）：

php composer.phar install

这将从composer.lock文件（如果存在）安装项目依赖项，或者依赖于composer.json。
