我目前正在尝试将带有Rails 5后端的角度2应用程序部署到heroku。为此，我一直在关注本教程：https://www.angularonrails.com/deploy-angular-2rails-5-app-heroku/#comment-39250。
在使用git push heroku master部署到heroku时，本教程一直在期待最后一部分。我收到以下错误：

这也是我的package.json，如教程中所做的那样：

我确信问题最有可能在于package.json并且无法找到'gulp'。
我也尝试按照以下人员的说明进行操作：https://www.angularonrails.com/deploy-angular-2rails-5-app-heroku/#comment-38286因为看起来他们有类似的问题 - 但是他们的说明看起来不是很清楚，而且无论我从他们没有工作。如果你知道他们的意思，请告诉我。
我很感激能得到的任何帮助。
非常感谢！

有点晚了，但我刚刚遇到这个错误，也做了同样的教程。如果您检查日志，则会看到以下错误：
未在package.json中指定节点版本
如果你谷歌，你会发现this page
使用package.json的engines部分指定要在Heroku上使用的Node.js的版本。
{
"name": "myapp",
"description": "a really cool app",
"version": "1.0.0",
"engines": {
"node": "6.9.4"
}
}
这应该让您的安装再次进行。
