Symfony - app_dev.php 中的 ClassNotFoundException

Question

在我的本地版本可以正常工作，但是当我放到服务器上时，出现了这个问题！请帮忙。

错误

App_dev.php 第 27 行中的 ClassNotFoundException： 试图从全局命名空间加载类“AppKernel”。 您是否忘记了“使用”声明，例如“Symfony\Bundle\FrameworkBundle\Tests\Functional\app\AppKernel”还是“Symfony\Bundle\SecurityBundle\Tests\Functional\app\AppKernel”？

我的 app_dev.php ：

<?php

    use Symfony\Component\HttpFoundation\Request;
    use Symfony\Component\Debug\Debug;

    // If you don't want to setup permissions the proper way, just uncomment the following PHP line
    // read http://symfony.com/doc/current/book/installation.html#configuration-and-setup for more information
    //umask(0000);

    // This check prevents access to debug front controllers that are deployed by accident to production servers.
    // Feel free to remove this, extend it, or make something more sophisticated.
    if (isset($_SERVER['HTTP_CLIENT_IP'])
        || isset($_SERVER['HTTP_X_FORWARDED_FOR'])
        || !(in_array(@$_SERVER['REMOTE_ADDR'], array('127.0.0.1', 'fe80::1', '::1')) || php_sapi_name() === 'cli-server')
    ) {
        header('HTTP/1.0 403 Forbidden');
        exit('You are not allowed to access this file. Check '.basename(__FILE__).' for more information.');
    }

    $loader = require_once __DIR__.'/../app/bootstrap.php.cache';
    Debug::enable();

    require_once __DIR__.'/../app/AppKernel.php';

    $kernel = new AppKernel('dev', true);
    $kernel->loadClassCache();
    $request = Request::createFromGlobals();
    $response = $kernel->handle($request);
    $response->send();
    $kernel->terminate($request, $response);

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 Ivory\CKEditorBundle\IvoryCKEditorBundle(),
            new FM\ElfinderBundle\FMElfinderBundle(),

            # Routing translate
            #new BeSimple\I18nRoutingBundle\BeSimpleI18nRoutingBundle(),

            $bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
            $bundles[] = new Sensio\Bundle\DistributionBundle\SensioDistributionBundle();

    /**

您似乎正在使用您的 app/boostrap.php.cache 文件作为自动加载，请更改以下行

$loader = require_once __DIR__.'/../app/bootstrap.php.cache';

到

$loader = require __DIR__.'/../app/autoload.php';

还请确保您的 composer.json 文件中存在以下代码

  "autoload": {
    "classmap": [
      "app/AppKernel.php",
      "app/AppCache.php"
    ]
  },
