在heroku上部署sinatra应用程序时出现问题

Question

我可以在heroku上部署我的基本sinatra应用程序，但运行它会出现“APP CRASHES”错误

运行“heroku logs”会出现以下错误。我使用的是ruby1.9.1。不知道为什么这个ruby1.8.7在回溯中显示。请帮助

- - - - ＆GT;您的应用程序需要一个找不到的文件。

   Most often this is due to missing gems, or it could be that you failed
   to commit the file to your repo.  See http://docs.heroku.com/gems for
   more information on managing gems.

检查此消息上方的回溯以进行调试。

Answer 1

创建一个名为“.gems”的文件，并包含此行“sinatra”。

通过这种方式你指示包括sinatra gem
