迁移时出错

我尝试运行db迁移,但出现以下错误

PG::UndefinedTable: ERROR:  relation "authie_sessions" does not exist

:ALTER TABLE“authie\u sessions”ADD“two\u factored\u at”timestamp/home/levi/。rvm/gems/ruby-2.4.1/gems/activerecord-5.1.5/lib/active\u record/connection\u adapters/postgresql/database\u语句。rb:73:in“async\u exec”

我的迁移文件是

class AddTwoFactorAuthFieldsToAuthie < ActiveRecord::Migration[4.2]
  def change
    add_column :authie_sessions, :two_factored_at, :datetime
    add_column :authie_sessions, :two_factored_ip, :string
    add_column :authie_sessions, :requests, :integer, :default => 0
    add_column :authie_sessions, :password_seen_at, :datetime
  end
end

我的数据库。yml是

default: &default
  adapter: postgresql
  encoding: utf8
  pool: 5
  username: postgres
  password: postgres
  database: staytus
  host: 127.0.0.1

production:
  <<: *default

development:
  <<: *default

test:
  <<: *default
  database: staytus_test

我正在使用postgresql
