Appkernel Symfony2出错

Question

我一直都会遇到同样的错误......我已经尝试过使用大家解决方案但没有运气 错误：AppKernel.php第17行中的ClassNotFoundException： 尝试加载课程＆＃34; AppBundle＆＃34;来自命名空间＆＃34; AppBundle＆＃34;。 你忘记了＆＃34;使用＆＃34;另一个名称空间的声明？

<?php
use Symfony\Component\HttpKernel\Kernel;
use Symfony\Component\Config\Loader\LoaderInterface;

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = [
            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 Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
            new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
            new AppBundle\AppBundle(),
            new OC\PlatformBundle\OCPlatformBundle(),
        ];

        if (in_array($this->getEnvironment(), ['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 getRootDir()
    {
        return __DIR__;
    }

    public function getCacheDir()
    {
        return dirname(__DIR__).'/var/cache/'.$this->getEnvironment();
    }

    public function getLogDir()
    {
        return dirname(__DIR__).'/var/logs';
    }

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

Answer 1

请检查您是否有目录AppBundle，如果该目录不存在，请从AppKernel.ph文件中删除此行：

new AppBundle\AppBundle(),

Answer 2

我认为您的AppBundle类没有（或严重）定义。你应该在src/AppBundle/AppBundle.php：

中有这个

<?php

namespace AppBundle;

use Symfony\Component\HttpKernel\Bundle\Bundle;

class AppBundle extends Bundle
{
}
