关于这是什么以及我如何修复它有什么想法吗

$ rake db:migrate
== 20150512132215 RenameNotificationSubscriptions: migrating ==================
-- rename_table(:notifications_subscriptions, :video_subscriptions)
rake aborted!
StandardError: An error has occurred, all later migrations canceled:

Mysql2::Error: Can't find file: './railsapp_development/notifications_subscriptions.frm' (errno: 2 - No such file or directory): RENAME TABLE `notifications_subscriptions` TO `video_subscriptions`/Users/mark/.rvm/gems/ruby-2.1.2/gems/activerecord-4.1.8/lib/active_record/connection_adapters/abstract_mysql_adapter.rb:303:in `query'

我的旧表名错误

notifications\u subscriptions

应该是

notification\u subscriptions

。尽管如此，这还是一个奇怪的错误
