# npm 或者 yarn安装vuecli3.0
npm install -g @vue/cli
# OR
yarn global add @vue/cli

vue create vue-cli3-ts

1.   node_modules //当前node模块存放处
 2.   public //index页面所在镜头文件也可以放这个里面
 3.   src //当前项目存放
        assets //静态文件存放
        components //组件存放
        views //项目存放
        types //存放接口声明
        app.vue //主要路由输入地方
        main //总的js文件
        router //路由文件
        shims-tsx.d //兼容jsx
        shims-vue.d //兼容vue
        store //vuex总文件
 4.   pakeage.js //文件（我们安装的依赖都再里面可以看到，也可以根据这个去下载node_modules）
 5.   我们还少一个vue.config.js 和 pakeage.js 同级
 6    tsconfig.json  ts的配置
