我目前正在尝试将带有Rails 5后端的angular 2应用程序部署到heroku。为了做到这一点，我一直遵循以下教程：

本教程在部署到heroku时使用：
git-push-heroku-master

如果能得到任何帮助，我将不胜感激

package.json中未指定节点版本

如果你用谷歌搜索，你会发现

使用package.json的engines部分指定要在Heroku上使用的Node.js版本

{
  "name": "myapp",
  "description": "a really cool app",
  "version": "1.0.0",
  "engines": {
    "node": "6.9.4"

这应该会让你的安装重新开始。

package.json中未指定节点版本

如果你用谷歌搜索，你会发现

使用package.json的engines部分指定要在Heroku上使用的Node.js版本

{
  "name": "myapp",
  "description": "a really cool app",
  "version": "1.0.0",
  "engines": {
    "node": "6.9.4"
}
}

这将使您的安装重新开始。
