迁移错误的</p> <p>$ Heroku的运行耙分贝部署

NoMethodError: undefined method `dump_schema_after_migration=' for ActiveRecord: 
:Base:Class

：迁移

我是新来的Heroku的部署，并没有能够解决它，请在解决它预先感谢帮助。

这就是我实际得到的。

$ heroku run rake db:migrate

这是完全错误跟踪：

你确定这是你唯一的错误”重新获得？你能发布完整的错误跟踪吗？ – Surya 2014-08-29 08:02:27

注意我在问题中添加了它的确切错误。 – Mukesh 2014-08-29 08:16:19

在这里：https://stackoverflow.com/questions/22707102/cannot-run-any-commands-on-my-heroku-app-migrate-console-etc我希望这有助于 – Surya 2014-08-29 08:37:09

假设你使用的是赖斯4，只是删除下面的代码在你的config/environments/production.rb

config.active_record.dump_schema_after_migration = false

试过，但它没有工作 – Mukesh 2014-08-29 08:16:41

你提交了修改后的文件，然后部署？ – RAJ 2014-08-29 08:29:47
