PS：vue.js有著名的全家桶系列，包含了vue-router，vuex， vue-resource，再加上构建工具vue-cli，就是一个完整的vue项目的核心构成。
使用Vue-cli是快速构建VUE项目
vue-cli是官方推荐的构建工具，简化了我们使用webpack的难度，并且支持热更新，所以我们只需要关注开发，从而省去了繁琐的服务重启以及webpack配置打包过程。
此处是vue-cli构建过程，git构建过程在文章末
//安装前需要配置node及npm环境
//全局安装 vue-cli 如果本机以前安装过 就无须执行避免重复安装
$ npm install --global vue-cli
//创建一个基于 webpack 的vue项目
$ vue init webpack vue-iview-master // 后续按回车安装默认即可
//进入到创建的vue项目
$ cd vue-iview-master
//安装依赖
$ npm install
//启动项目
$ npm run dev //启动成功 http://localhost:8080 即可打开测试首页我的构建过程

当前项目根目录执行命令
$ npm install --save iview引入iview
src/main.js
// The Vue build version to load with the `import` command

Vue.use(iView) //使用iview组件
/* eslint-disable no-new */
new Vue({

}2 Mixed spaces and tabs错误
原因是项目构建时设置eslint，主要是因为代码不规范报错。缩进不规范，分号不需要等原因
最好是在项目构建时 Use ESLint to lint your code? (Y/n) 这一步选no

在 config/index.js 里配置 useEslint: false
useEslint: false,解决错误后启动项目
