Rails服務器不能在一個項目上工作，但可以在另一個項目上工作

Question

我的Rails服務器不適用於一個項目，但是可以爲另一個項目工作。

對於不工作，當我在終端運行軌道S上的項目中，我得到了下面的輸出：

=> Booting Thin 
=> Rails 4.1.0 application starting in development on http://0.0.0.0:3000 
=> Run `rails server -h` for more startup options 
=> Notice: server is listening on all interfaces (0.0.0.0). Consider using 127.0.0.1 (--binding option) 
=> Ctrl-C to shutdown server

該項目需要版本2.1.3紅寶石工作，雖然。

任何人都可以幫我嗎？

Answer 1

根據該錯誤消息：

config.allow_comments在ActiveAdmin 1.x中不再提供改爲使用config.comments。

所以，你需要編輯config/initializers/active_admin.rb和更改：

config.allow_comments 

到：

config.comments
