Ruby on rails psych.rb:370中的Rails服务器错误

我在Mac电脑上运行，任何帮助都将不胜感激。 当我尝试启动Rails服务器时，出现以下错误：

Richards-MBP:learn-rails richardxxxx$ rails server
=> Booting WEBrick
=> Rails 4.2.1 application starting in development on http://localhost:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server
