我正在本书中进行演练，在顶部构建一个带有Angular 2的Rails API应用程序。 Github
按照Angular For Rails开发人员手册中的说明使用两个buildpack。
heroku buildpacks:add https://github.com/jasonswett/heroku-buildpack-nodejs
heroku buildpacks:add heroku/ruby
我的所有更新都已签入。当我git push heroku master时，我收到以下错误打印输出

我在教程中添加的唯一内容是引擎定义，但是如果我在部署时遇到问题，Heroku就说要将其放入（以匹配我的本地版本）。
＆＃34;引擎＆＃34;：{ ＆＃34; node＆＃34;：＆＃34; 6.6.0＆＃34;， ＆＃34; npm＆＃34;：＆＃34; 3.10.3＆＃34; }，
有关如何推进部署的任何提示都很棒。谢谢！
更新 从
更改了package.json"heroku-postbuild": "ng build"
到
"heroku-postbuild": "ng build -prod"
它部署得很好。还有其他问题w Uglifier gem，但这个问题得到了解决。谢谢@jasonswett
