Question

为了尝试进入Angular 2，我试图从Angular 2的快速入门指南开始。我克隆了repo，更新了节点到6.9.1（使用npm 3.10.8），但是当我运行npm start时，我得到以下错误：

> angular-quickstart@1.0.0 start C:\WAMP\www\ng2quickstart
> tsc && concurrently "tsc -w" "lite-server"

我在线看到了一些问题（很多是通过StackOverflow），建议我将npm start命令更改为

"start": "concurrently \"npm run tsc:w\" \"npm run lite\" ",

但这给了我同样的错误。

我可以单独运行每个命令，它们似乎没有错误，所以我可以开始开发，但我很想知道这个问题，所以我可以更好地理解node / npm。

确保已安装并发软件包。运行以下命令以全局安装它：

npm install -g concurrently

节点命令单独工作但不同时工作（Angular Quickstart）
