关于symfony：Symfony2-作曲家弄乱了我的网站，因为所有捆绑包都不存在

Symfony2 - Composer messed up my site as all bundles don't exist

在开始使用Composer之前，我的Symfony2设置一切都很棒。

我确实在Composer上安装了Symfony2，但随后手动添加了捆绑软件-包括我自己创建的捆绑软件。

然后，我需要添加一些使用Composer似乎更容易的东西。后来在终端中发生了很多混乱，然后我在浏览器中运行时发现AppKernel.php中出现错误，提示不存在任何捆绑软件-包括：

1	FatalErrorException: Error: Class 'Acme\\DemoBundle\\AcmeDemoBundle' not found in /path/app/AppKernel.php line 39

我是100％的文件夹，除了运行各种Composer命令外，没有任何改变。

Composer没有对这些捆绑软件的引用。

我该如何解决？我猜我要么告诉Composer清除(像以前一样)，要么以某种方式让Composer理解这些捆绑软件。

我猜这与引导文件有关。我相信Composer将在更新后创建一个，但这就是我在努力的地方。
