闲聊：
今天是六一儿童节哟，小颖祝大家节日快乐哈哈哈。其实这个demo小颖断断续续做了将近两个礼拜了，心塞的，其实这个也没有多难，主要是小颖有点最近事情有点多，所以就把这个一直拖着，今天好不容易做好了嘻嘻。我们一起来看看效果图吧：
相关技术：
1.vue2.0
2.webpack
3.element
vue2.0环境搭建：
1.检查本地是否安装node：node -v
如果没有安装从node官网上下载相应的node，安装成功即可。
2.检查本地npm版本：npm -v，如果版本太低可以通过：npm install -g npm进行升级
3.全局安装webpack：npm install webpack -g
4.安装vue脚手架：npm install vue-cli -g
5.新建空文件夹，根据模板创建项目：
vue init webpack-simple 工程名字<工程名字不能用中文>
或者创建 vue1.0 的项目： vue init webpack-simple#1.0 工程名字<工程名字不能用中文>
会有一些初始化的设置，如下输入:
Target directory exists. Continue? (Y/n)直接回车默认(然后会下载 vue2.0模板，这里可能需要连代理)
Project name (vue-test)直接回车默认
Project description (A Vue.js project) 直接回车默认
Author 写你自己的名字
Use sass 小颖的这个demo要用sass所以，小颖选的yes，大家可以根据自己的需求选择yes or no
在你的项目根目录下，运行：npm run dev之后，会自动打开你的默认浏览器：http://localhost:8080/ 效果如下：
项目目录：
------------------mydemo
--------------------------src
----------------------------------page
--------------------------------------------------menu1
---------------------------------------------------------------------menuTab.vue
--------------------------------------------------menu2
---------------------------------------------------------------------menuTable.vue
--------------------------------------------------404.vue
--------------------------------------------------home.vue
--------------------------------------------------login.vue
----------------------------------App.vue
----------------------------------main.js
----------------------------------router.js
--------------------------favicon.ico
--------------------------index.html
--------------------------package.json
--------------------------webpack.config.js
然后我们将自己想要的页面什么的慢慢加进去：
1.在根目录下添加favicon.ico图标，小颖是直接把：mydemo/src/assets下的logo.png改成favicon.ico。
2.在webpack.config.js中添加以下代码：
然后我们再执行一次：npm run dev
然后就报错啦报错啦：
解决方法：
执行npm install html-webpack-plugin -save-v
3.在index.html中引入favicon.ico图标：
<link rel="shortcut icon" href="favicon.ico"/>
4.新增所需vue文件和js文件：
5.引入所需的npm：element-ui、vue-router、font-awesome、style-loader。
最后呢我们一起来看看具体哪些重要的vue文件和js文件代码是什么样子的。
代码来啦：
webpack.config.js
var path = require('path')
var webpack = require('webpack')
var HtmlWebpackPlugin = require('html-webpack-plugin')

如果这篇文章对你有用请给小颖一点鼓励吧嘻嘻，动动手扫扫下方二维码小颖打赏一丢丢呗，欢迎帅锅美女打赏哦！
bug一个大大的bug
由于小颖的疏忽，小颖，少写了一个方法，所以会出现
这样的问题。原因是由于小颖在home.vue中少写了一个 “showMenu” 方法，嘻嘻，谢谢这位园友，小颖已经把博客更新啦，嘻嘻，小颖也是初学者所以希望大家多多提问题和建议哦。
