1、打开系统命令窗口（默认目录是：C:\Users\***）

2、创建文件夹命令：mkdir angular-quickstart

3、跳转目录命令：cd angular-quickstart

4、手动创建一个package.json文件（命令创建一个package.json文件：npm init），复制以下内容到package.json

{  "name": "angular2-quickstart",  "version": "1.0.0",  "scripts": {    "tsc": "tsc",    "tsc:w": "tsc -w",    "lite": "lite-server",    "start": "concurrent \"npm run tsc:w\" \"npm run lite\" "  },  "license": "ISC",  "dependencies": {    "angular2": "2.0.0-beta.3",    "systemjs": "0.19.6",    "es6-promise": "^3.0.2",    "es6-shim": "^0.33.3",    "reflect-metadata": "0.1.2",    "rxjs": "5.0.0-beta.0",    "zone.js": "0.5.11"  },  "devDependencies": {    "concurrently": "^1.0.0",    "lite-server": "^2.0.1",    "typescript": "^1.7.5"  }}

5、打开命令行，angular2-quickstart目录下输入npm install，然后等着就行了

6、配置Typescript，手动创建一个tsconfig.json文件（命令创建一个tsconfig.json文件：tsc --init 或 tsc -init），复制以下内容到tsconfig.json

{  "compilerOptions": {    "target": "es5",    "module": "system",    "moduleResolution": "node",    "sourceMap": true,    "emitDecoratorMetadata": true,    "experimentalDecorators": true,    "removeComments": false,    "noImplicitAny": false  },  "exclude": [    "node_modules"  ]}

7、在angular2-quickstart目录下建一个文件夹app，并在app文件夹里建一个文件叫app.component.ts，复制以下内容到app.component.ts

import {Component} from 'angular2/core';@Component({    selector: 'my-app',    template: '<h1>My First Angular 2 App</h1>'})export class AppComponent { }

8、在app目录下建一个文件叫main.ts，复制以下内容到main.ts

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

9、在angular2-quickstart目录下建一个html文件叫index.html，复制以下内容到index.html

<html>  <head>    <title>Angular 2 QuickStart</title>    <meta name="viewport" content="width=device-width, initial-scale=1">        <!-- 1. Load libraries -->    <!-- IE required polyfills, in this exact order -->    <script src="node_modules/es6-shim/es6-shim.min.js"></script>    <script src="node_modules/systemjs/dist/system-polyfills.js"></script>    <script src="node_modules/angular2/bundles/angular2-polyfills.js"></script>    <script src="node_modules/systemjs/dist/system.src.js"></script>    <script src="node_modules/rxjs/bundles/Rx.js"></script>    <script src="node_modules/angular2/bundles/angular2.dev.js"></script>    <!-- 2. Configure SystemJS -->    <script>      System.config({        packages: {                  app: {            format: 'register',            defaultExtension: 'js'          }        }      });      System.import('app/main')            .then(null, console.error.bind(console));    </script>  </head>  <!-- 3. Display the application -->  <body>    <my-app>Loading...</my-app>  </body></html>
