新建项目

在node和vue都调试、配置好的情况下使用vscode 在终端中输入命令

npm i –g @vue/cli 安装vue脚手架

安装成功后通过vue —version 可以查看版本

vue create 项目名 新建项目

vue create control

空格为取消选项 回车为选中

根据个人习惯选择css样式 本人喜欢使用sass

一路回车等待创建

此界面为创建成功

cd control 来到项目的目录 进行启动 （git命令自行学习）

此界面为开启成功

项目初始化

将以下标记全部删除

router/index.js最终页面

将views中文件全部删除，并新建Login.vue 和 Register.vue 文件，修改App.vue

Login 、 Register 和 App.vue 文件代码

// Login、Register和App.vue 文件代码
<template>
  <div>
    Login // Register 
  </div>
</template>
<script>
  export default {}
</script>
<style lang="scss" scoped>

</style>

在router/index.js中配置路由信息

在App.vue中添加路由出口 <router–view></router–view>

此时打开在浏览器打开项目 为此界面即为成功

页面部署

引入element–ui

element–ui 哪里需要引哪里

代码
