我在rails应用程序上运行我的ruby，它运行正常。由于某些应用程序要求，我必须在config文件夹中的application.yml文件中进行更改。所以我在application.yml.example文件中进行了这些更改，然后用application.yml.example替换了现有的application.yml文件。
所以新的application.yml有我想要的所有修改。但在此之后，当我运行我的应用程序时，Phusion乘客给了我错误：
application.yml not found, see config/application.yml.example
但application.yml存在于我的应用程序中，我刚刚修改了它的内容。
这是我的日志文件：
