ruby-on-rails – 在生产服务器上撬 – 我怎样才能让它在那里工

我可以使用binding.pry在本地调试应用程序就好了.但我也需要在远程服务器(网站)上,因为在本地我没有任何错误,但在生产我做.所以把binding.pry放在服务器上的源文件中,当我向网站发出帖子请求时,我没有返回任何响应,即使我在服务器上运行rails console也没有改变任何东西而且没有输出在rails控制台中.

它是一个开发服务器,所以它在互联网上可见,但它是一个开发人员服务器,虽然对于rails它的生产,因为RAIL_ENV等于生产.我真的需要以我在本地使用pry的方式进行调试.我该怎么做？

更新：
