我是RoR的初学者，我正在努力让rails服务器正常工作。每次我运行命令
rails server
总是显示所有这些行
C:\Users\Familia-PC\RoR\holamundo>rails server
=> Booting WEBrick
=> Rails 4.1.1 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

将它放在你的gemfile中：
gem "tzinfo-data"
