將symfony 2應用推送到heroku，由遠程主機關閉

我想把我的應用在Symfony 2 PHP中寫入到heroku服務器。我使用Ubuntu 14.04。當我推我的應用程序時，我看到：將symfony 2應用推送到heroku，由遠程主機關閉

-----> PHP app detected

也許這是我的網絡提供商故障？

UPDATE 我有omposer.lock在我的項目目錄，我的composer.json是：

以及您在composer.json文件中需要什麼版本的PHP？ – cmorrissey

發佈你的composer.json，你有沒有composer.lock文件？ –

@SeanKeane我更新了我的問題 –
