ruby-on-rails - rake db:migrate:up 版本错误

Question

我创建了一个带有整数、字符串的退款模型，当我尝试迁移这个新表时，出现以下错误。

rake db:migrate:up VERSION=20130806144409



rake aborted!

我的迁移文件名20130806144409_create_refunds.rb

这就是里面的内容

class CreateRefunds < ActiveRecord::Migration
  def change
    create_table :refunds do |t|
      t.integer :job_id
      t.integer :customer_id
      t.integer :amount

      t.timestamps
    end
  end
end
