好吧，我在Heroku上部署了一个非常基本的应用程序。我严格按照tutorial的要求进行了部署。关于这个部署的一切都是教科书式的，但是当我打开Heroku上的网站时，我得到了一条令人沮丧的模糊消息：“很抱歉，出了问题。”
当我做“英雄ps”的时候它说：

Process  State       Command                               
    -------  ----------  ------------------------------------  
    web.1    up for 13m  bundle exec rails server thin -p $..

字符串
当我运行“heroku logs”时，我得到了通常的弃用消息，然后是下面的文本。但是我没有在这些日志中看到任何会导致应用程序崩溃的红旗。我错过了什么吗？
