Ruby on rails ArgumentError:将Rails 5应用程序部署到Heroku时，选项无效：harmony

我是Heroku的新手，由于一个与丑陋相关的错误，我在部署Rails 5应用程序的更新版本时遇到了问题

我目前在Heroku上部署了我的应用程序的一个版本，但没有加载我的JS文件。它们可以在localhost:3000上正常加载和运行

我认为这是一个与丑陋有关的问题。在读了另一个人的类似文章后，我尝试了他降低丑陋宝石等级的解决方案；我的Gemfile之前指定了'>=1.3.0'，因此Heroku已经自动安装了4.1.20。因此，我将我的Gemfile更改为：gem'uglifier'，“~>3.0.4”）

但是，当我现在推到Heroku时，会收到以下错误消息：
