将Symfony 2.5.7部署到heroku Cloud - 找不到类'Doctrine\Bundle\DoctrineBundle\DoctrineBundle'

我正在尝试将我的Symfony应用程序部署到heroku并遵循Deploying to Heroku教程 .

但是，当我将我的代码发送到我的heroku应用程序时，heroku无法编译我的应用程序，并且在收到来自 composer.json 的软件包后，我收到以下消息：

创建“app / config / parameters.yml”文件PHP致命错误：第16行上的/tmp/build_45216c70c70215d5009d6aaa12fb90c1/app/AppKernel.php中找不到类'Doctrine \ Bundle \ DoctrineBundle \ DoctrineBundle'脚本Sensio \ Bundle \ DistributionBundle \ Composer \ ScriptHandler :: clearCache处理以异常终止的post-install-cmd事件[RuntimeException]执行“'cache：clear --no-warmup'”命令时发生错误 .

这是我 composer.json 的内容：

当我在本地机器上安装供应商时，我可以在 vendor/doctrine/doctrine-bundle/Doctrine/Bundle/DoctrineBundle/DoctrineBundle.php 中找到 DoctrineBundle 类，所以我不明白这个错误： - （....

谢谢
