在开发模式下工作正常。但是，当我执行rails s生产命令时，我有以下错误消息：

rails s production

我认为这与错误的最后一行有关：

5.1.4/lib/active_support/dependencies.rb:292:in `require': cannot load such file -- rack/handler/production (LoadError)

我试图在没有任何结果的情况下使用activesupport gem。我正在运行Ruby on Rails 5.1.4，rvm运行ruby 2.5.1。我的操作系统是ubuntu 14.04。

正确的命令是：

rails server -e production

或者您可以使用完整选项执行此操作：

rails s -e production -p [your port] -b [your ip address] -P tmp/pids/test.pid

在生产中无法运行rails
