简介
5 分钟从0搭建一个ng2项目demo
https://angular.io/docs/js/latest/quickstart.html
你运气真好，竟然看到了这篇文章，你省事了，一分钟让你完成，请点击https://github.com/1329555958/angular2-quickstart
具体步骤
假定你已经具备了nodejs环境；
- 新建目录结构
angular2-quickstart|----app| |----app.component.js| |----boot.js|----index.html|----package.json
- 修改package.json(npm 相关，如果看不懂这里面的内容请关注nodejs)
- 安装依赖
npm install在package.json同级目录下执行（我假装你不知道在哪里执行）
执行的时候可能有红色字体的警告，无视它们，最后会成功的 - 修改app.component.js
- 修改boot.js
- 修改index.html
此时你发现你的目录多出了node_modules及下面一些目录；
运行npm start，你的默认浏览器会打开一个页面，http://localhost:3000 ,如果没有，可以联系我；
恭喜你！你很棒，累了吧，休息会，稍后我们再细聊具体细节!
