搭建 vue-cli 腳手架

安裝 git
安裝 node 並配置環境變量，使用 zip 版本css
```
# 檢查 node 是否安裝成功 
node -v
```

使用淘寶鏡像vue

npm config set registry https://registry.npm.taobao.org
# 檢查是否配置成功
npm config get registry

安裝 node 模塊 cnpmnode

npm install -g cnpm --registry=https://registry.npm.taobao.org

全局安裝 vue-cliwebpack

cnpm install vue-cli -g
# 檢查是否安裝成功
vue

使用 webpack 骨架初始化應用，就像 maven 骨架同樣git
```
mkdir test && cd test
vue init webpack
```
運行項目web
```
npm run dev
```

引入 Element-ui

修改 main.jsvue-cli

import Vue from 'vue'
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'
import App from './App'
import router from './router'


Vue.config.productionTip = false

Vue.use(ElementUI)


/* eslint-disable no-new */
new Vue({
  el: '#app',
  router,
  components: { App },
  template: '<App/>'
})

其實只改動了三處shell

import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'

Vue.use(ElementUI)

注意事項：數據庫

/ eslint-disable no-new / 註釋不能刪除，否則報錯
最底部必需要有一空行，否則編譯不過
縮進空格數必須一致，否則報錯

接下來就能夠把 vue 官網的組件拿到 HelloWorld.vue 中去玩了，好比我把它弄成了這樣npm

<template>
 <el-container style="height: 500px; border: 1px solid #eee">
  <el-aside width="200px" style="background-color: rgb(238, 241, 246)">
