angular - npm 启动 : Failed start script 'ng serve'

Question

Just to clarify this: I'm completely new to AngularJS and to any Web Technology. I'm a beginner when it comes to Web Development.

I tried to install it and I've gotta admit, after many "Unknown Buttons Pressings", I may have done a big mess, or maybe not.

我按照 AngularJS 网站的教程 安装了 Angular，然后我只想按下“红色按钮”:

npm start

但它抛出一个错误说:

这里是实际的 Debug_Log:

24 error Or if that isn't available, you can get their info via:
24 error     npm owner ls apanpie
24 error There is likely additional logging output above.
25 verbose exit [ 1, true ]

所以我搜索了整个 Google Globe，但一无所获。

此外，我不知道这是否相关，但在我的 TypeScript 代码中:

import { View, Component } from '@angular2/core';
[... Components Here ... ]

它抛出一个错误:

Cannot find module '@angular2/core'

如果有人能开导我，我会很高兴!

如果您刚刚开始使用 angular 2，请按照 angular 网站上提到的这些步骤进行操作。

1 从这里下载启动项目。将它保存到本地文件夹让我们说 c:\test\。位置 = https://github.com/angular/quickstart.git快速入门 这就是您需要为 hellp world 应用程序做的所有事情。

2) 转到命令提示符，然后 cd c:\test 。3) 如果没有安装，请安装 node js。4) npm 安装5) npm 启动

这将显示您的第一个 angular 2 hello world 应用。
