我刚刚将我的应用升级到Rails 6.0，现在无法推送到Heroku

我的推送显示此错误：

remote:  !     Push rejected, failed to compile Ruby app.
remote: 
remote:  !     Push failed
remote: Verifying deploy...
remote: 
remote: !   Push rejected to aloop-staging.

但如果我在Heroku上查看我的活动日志，它会说：

然而，这很奇怪，因为在我的

Gemfile.lock中它说：
RUBY VERSION
   ruby 2.6.3p62

BUNDLED WITH
   2.0.2

当我使用ruby-v
和bundler-v
时，这一点就得到了证实。有人知道为什么这个推送被拒绝了吗？
结果我不得不更新构建包：
heroku构建包：设置heroku/ruby

在以后的过程中仍然存在问题，但这似乎解决了这个具体问题
