創(chuàng)建應用程序的項目文件夾和定義包的依賴關(guān)系和特殊項目設(shè)置

Create the app’s Angular root component

Add main.ts, identifying the root component to Angular

Add index.html, the web page that hosts the application

Build and run the app

touch package.json
touch tsconfig.json 
touch typings.json
touch systemjs.config.js
touch index.html
touch styles.css
mkdir app
touch app/app.component.ts
touch app/main.ts
