Question

您好，并提前感谢您参加比赛的时间，

我是RoR的新手，我正在跟随Michael Hartl关注RUBY ON RAILS TUTORIAL，当我试图在heroku中迁移db时，我真的遇到了这个错误（我知道语法错误意味着什么（END），但我仍然无法解决它）

heroku run rake db:migrate

Running `rake db:migrate` attached to terminal... up, run.4787
Migrating to CreateUsers (20141001220747)

我已经完成了我的研究，并发现问题是额外或缺少END，但我尝试添加和删除结束......没有运气。奇怪的是，即使我添加或删除ENDS，错误也完全相同。这是迁移文件

class CreateUsers < ActiveRecord::Migration
  def change
    create_table :users do |t|
      t.string :name
      t.string :email
      t.timestamps
    end
  end
end

非常感谢，希望你能提供帮助。快乐的编码

发现问题!!!! yay很高兴问题是我必须提交更改，将它们推送到git然后heroku，一旦我这样做，我可以运行db迁移而没有任何问题...

顺便说一句，我发布在顶部的代码是正确的，但是我第一次推它时，它定义了类的语法错误。
