src/views/index/index.vue

这个地方是我放整个全局框架的地方 , 引入标签页组件就可以了 , 我就不放代码了
在这里插入图片描述

src/main.js

将这些组件挂载到main上 , 然后下载相应的依赖包
在这里插入图片描述

我这里推荐用npm下载
下载vuex依赖包
npm install vuex --save
下载router依赖包
npm install vue-router
组件用的是sass , 所以下sass的依赖包
npm i sass-loader -D
npm install node-sass
我的样式用的是element UI
npm i element-ui -S

下载相应的依赖就没有问题了, 标签页就可以正常的使用了
