Question

我正在尝试学习如何将一个Node和Angular应用程序部署到Heroku并且收到错误。

以下是我正在采取的步骤

在GitHub上创建一个空的回购。
部署预创建project，创建一个新的heroku应用。

接下来，我下载并复制预先创建的project中的代码。

然后我将该代码推送到我创建的第一步的空仓库。

然后我回到Heroku并手动部署将我的回购连接到它。

部署时，我得到一个我不知道如何解决的错误。这对我来说很奇怪，因为我有预配置的Heroku应用程序以及完全相同的代码。

我今天在部署到Heroku时遇到了这个问题。在package.json中，确保正确地将节点指定为引擎。例如：

"engines": {
  "node": "^8.0.0"
},

将Node和Angular部署到Heroku错误
