我只是关注 > 2.2

当我运行$ rails generate scaffold User name:string email:string时，什么也没发生，终端只是挂在那里，我按ctrl+C取消命令，显示如下：

➜ toy_app git:(master) rails generate scaffold 用户名：string email：string ^C/Users/duodian/.rvm/gems/ruby-2.3.0/gems/spring-1.7.2/lib/spring/client/run.rb:117:in 得到： 从 /Users/duodian/.rvm/gems/ruby-2.3.0/gems/spring-1.7.2/lib/spring/client/run.rb:117:in verify_server_version 中断 来自 /Users/duodian/.rvm/gems/ruby-2.3.0/gems/spring-1.7.2/lib/spring/client/run.rb:62:in run 来自 /Users/duodian/.rvm/gems/ruby-2.3.0/gems/spring-1.7.2/lib/spring/client/run.rb:42:in warm_run 来自/Users/duodian/.rvm/gems/ruby-2.3.0/gems/spring-1.7.2/lib/spring/client/run.rb:35:in call 来自/Users/duodian/.rvm/gems/ruby-2.3.0/gems/spring-1.7.2/lib/spring/client/command.rb:7:in call 来自/Users/duodian/.rvm/gems/ruby-2.3.0/gems/spring-1.7.2/lib/spring/client/rails.rb:24:in call 来自/Users/duodian/.rvm/gems/ruby-2.3.0/gems/spring-1.7.2/lib/spring/client/command.rb:7:in call 来自 /Users/duodian/.rvm/gems/ruby-2.3.0/gems/spring-1.7.2/lib/spring/client.rb:30:in run 来自/Users/duodian/.rvm/gems/ruby-2.3.0/gems/spring-1.7.2/bin/spring:49:in 来自/Users/duodian/.rvm/gems/ruby-2.3.0/gems/spring-1.7.2/lib/spring/binstub.rb:11:in load' 来自/Users/duodian/.rvm/gems/ruby-2.3.0/gems/spring-1.7.2/lib/spring/binstub.rb:11:in 来自 /Users/duodian/Desktop/toy_app/bin/spring:15:in 要求' 来自 /Users/duodian/Desktop/toy_app/bin/spring:15:in ' 从 bin/rails:3:in load 从 bin/rails:3:in
