在开始之前，我应该声明我只编写了6个月，所以请原谅任何新手的错误。
问题：我一直在使用React.js，webpack和node.js服务器构建个人网站这个简单的article。这是我的第一个React项目，开发阶段进展顺利。但是，我无法完成文章中概述的最后一步，即在Heroku上构建和部署我的应用程序。
当我在本地运行它时，该应用程序工作正常，所以我认为该问题与我为Heroku配置应用程序的方式有关。
命令行错误：我的Heroku遥控器准备好接收我的应用程序，我试图推送我的最新提交并收到以下命令行错误：
$ git push heroku master ‹ruby-2.4.2›

我做了什么：
i）我尝试安装npm-shrinkwrap，看看锁定依赖项是否有帮助。它没。
ii）我还更改了Heroku的默认配置，其中包括NPM_CONFIG_PRODUCTION = true＆＃39; to＆＃39; NPM_CONFIG_PRODUCTION = false＆＃39;，因为我希望devDependencies包含在Heroku上安装的节点模块。
任何帮助都会受到大力赞赏。
