我有：
打字稿1.7.5版本
节点0.12.2提供版本

也许有人可以帮助解决这个问题:)？

解决方案

为了让 NPM启动我跑，我必须确保我已经在全球安装了一些的devDependencies。您是否尝试过：

NPM安装-g同时

NPM安装精简版-g服务器

NPM安装-g打字稿

I know Angular2 beta has just been released but I can't reproduce the steps from their official site tutorial ( https://angular.io/docs/ts/latest/quickstart.html ). Maybe someone has had similar issues and knows what to do in order to fix the this? When I try to start the application with npm start command I get output like this:

I had:typescript 1.7.5 versionnode 0.12.2 version

Maybe someone could help solve the problem :) ?

export class AppComponent {}

boot.js:

import {bootstrap} from 'angular2/platform/browser'
import  {AppComponent} from './app.component'

bootstrap(AppComponent);

解决方案

In order to get npm start running for me, I had to make sure I had globally installed some of the devDependencies. Have you tried:

npm install -g concurrently
npm install -g lite-server
npm install -g typescript
