刚刚更新到 symfony3.0 得到 php 致命错误 class 未找到

Question

我在 php5.6 和 symfony 2.7 中，现在升级到 php7 和 symfony3 配置仅此而已。

我收到这个错误，似乎命名空间和自动加载系统有问题：

PHP Fatal error:  Uncaught Error: Class 'Symfony\Bundle\FrameworkBundle\FrameworkBundle' not found

似乎无法找到正在发生的事情，因为除了 composer.json 之外我没有更改任何东西来更新。

这是我的作曲家：

请告诉我我做错了什么，如果我确实遗漏了什么，我在哪里可以找到迁移文档

将 SensioDistributionBundle 版本升级到 5.0 需要对您的自动加载配置进行一些额外更改（请参阅 https://github.com/symfony/symfony-standard/blob/2.8/UPGRADE-2.8.md）。

看看 https://github.com/symfony/symfony-standard/pull/869 and https://github.com/symfony/symfony-standard/pull/897 中 Symfony 标准版所做的更改。
