ruby-on-rails – heroku db：migrate aborted

我是 Ruby on Rails和heroku的新手.我按照视频教程中的步骤进行操作.我认为我没有做任何不同的事情.但是,我无法在heroku上运行rake db：migrate,而一切都在我的localhost：3000上运行
您还可以详细说明GEMFILE.lock和GEMFILE的功能.

$heroku run rake db:migrate

解决方法

这与您的代码或ruby在轨道上没有任何关系.

它是一个DNS错误,如果你有你的rails应用程序和Heroku中的数据库(这是默认的),然后尝试达到heroku支持,并继续尝试,一旦dns更新它应该工作,但以防万一,尝试联系Heroku支持,他们应该能够很快解决问题.
