我执行了重置数据库的命令后，试图创建新的用户 name: "Example User 1", email: "[email protected]"，出现以下错误


C:\Users\pcjjdy\Desktop\ruby\lab6\mytwitter>rails console
DL is deprecated, please use Fiddle
Loading development environment (Rails 4.0.0)
irb(main):002:0>User.create(name: "Example User 1", email: "[email protected]",password: "secret", password_confirmation: "secret")
NameError: uninitialized constant User
        from (irb):1

        from bin/rails:4:in `require'
        from bin/rails:4:in `<main>'

网上有人说是 gemfire 问题，也有人说是 application.rb 的问题。我尝试过但都无效。求指教

如果是你 Ruby, Rails 新手，请别在 Windows 上面折腾：https://ruby-china.org/topics/1020

你 user model 创建了吗？

另外，请善用 Linux

如果实在脱离不了 windows 工作环境，可以在 windows 上面装个 vagrant，虚拟机跑 linux，运行环境在 vagrant linux 里面，开发在 windows 里面，两不误

同样的问题，新建的 Model。报这个错
