php - Symfony2 自动加载器找到文件但没有找到类

Question

我试图在没有供应商的情况下安装 symfony2，但在运行 app_dev.php 时我不断收到以下错误:

RuntimeException: The autoloader expected class "Symfony\Component\EventDispatcher\Event" to be defined in file "/var/www/caremonk/vendor/symfony/symfony/src/Symfony/Component/EventDispatcher/Event.php". The file was found but the class was not in it, the class name or namespace probably has a typo.

我已经通过以下方式安装了正确的文件和供应商: php composer.phar 更新 php composer.phar 安装

我还检查了 Symfony2 提示的文件，文件的内容是:

<?php

/*

 *
 * (c) Fabien Potencier <fabien@symfony.com>

 */

namespace Symfony\Component\EventDispatcher;

/**
 * Event is the base class for classes containing event data.
 *
 * This class contains no event data. It is used by events that do not pass
 * state information to an event handler when an event is raised.
 *
 * You can call the method stopPropagation() to abort the execution of
 * further listeners in your event listener.

class Event
{
   // Some more code
}

这是一个标准的 symfony2 类，我还没有接触过，所以我对我需要做的事情有点迷茫。我怎样才能摆脱这个错误？

昨晚遇到了类似的问题。禁用并重新启用 APC 似乎可以解决问题。
