Heroku推被拒绝 - rails 5 app

Question

我无法弄清楚为什么我一直收到这个错误。 我已经尝试修改buildpack，Gemfile和database.yml，但不断收到相同的消息：

Answer 1

你是否在你的Gemfile上加入了ruby版本？ 红宝石'2.2.4'

Answer 2

在创建Heroku应用程序时，您似乎没有设置buildpack。 根据Heroku文档，您可以手动设置它

heroku buildpacks:set heroku/ruby

Answer 3

我有同样的问题并通过Inistalizing并再次提交git然后使用heroku create部署rails app来解决它
