我有一个奇怪的问题.我刚刚在远程服务器上配置了rails项目.但是在我运行’rails server’命令后立即出现此错误：

[pediatric-nutri]# rails server
=> Booting WEBrick
=> Rails 4.1.16 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
Exiting
/home/lookwhat/rails_apps/pediatric-nutri/app/controllers/application_controller.rb:5:in `<class:ApplicationController>': undefined method `decent_configuration' for ApplicationController:Class (NoMethodError)
    from /home/lookwhat/rails_apps/pediatric-nutri/app/controllers/application_controller.rb:1:in `<top (required)>'
    from /usr/local/rvm/gems/ruby-2.3.1/gems/activesupport-4.1.16/lib/active_support/dependencies.rb:443:in `load'

解决方法

也许服务器端将您的decent_exposure更新为不同版本的API(V2到V3).有关它的更多细节
here特别是你可能面临的问题升级部分.
