這里文檔要這樣看：

這里

npm install ant-design-vue@2.0.0-rc.3 -savenpm install axios@0.21.0 --save

在main.js中添加antd.css及Antd

import { createApp } from 'vue' import App from './App.vue' import Antd from 'ant-design-vue'; import 'ant-design-vue/dist/antd.css';const app = createApp(App); app.use(Antd).mount('#app');

修改App.vue

<template><a-layout><a-layout-header class="header"><div class="logo" /><a-menutheme="dark"mode="horizontal"v-model:selectedKeys="selectedKeys1":style="{ lineHeight: '64px' }"><a-menu-item key="1">nav 1</a-menu-item><a-menu-item key="2">nav 2</a-menu-item><a-menu-item key="3">nav 3</a-menu-item></a-menu></a-layout-header><a-layout><a-layout-sider width="200" style="background: #fff"><a-menumode="inline"v-model:selectedKeys="selectedKeys2"v-model:openKeys="openKeys":style="{ height: '100%', borderRight: 0 }"><a-sub-menu key="sub1"><template #title><span><user-outlined />subnav 1</span></template><a-menu-item key="1">option1</a-menu-item><a-menu-item key="2">option2</a-menu-item><a-menu-item key="3">option3</a-menu-item><a-menu-item key="4">option4</a-menu-item></a-sub-menu><a-sub-menu key="sub2"><template #title><span><laptop-outlined />subnav 2</span></template><a-menu-item key="5">option5</a-menu-item><a-menu-item key="6">option6</a-menu-item><a-menu-item key="7">option7</a-menu-item><a-menu-item key="8">option8</a-menu-item></a-sub-menu><a-sub-menu key="sub3"><template #title><span><notification-outlined />subnav 3</span></template><a-menu-item key="9">option9</a-menu-item><a-menu-item key="10">option10</a-menu-item><a-menu-item key="11">option11</a-menu-item><a-menu-item key="12">option12</a-menu-item></a-sub-menu></a-menu></a-layout-sider><a-layout style="padding: 0 24px 24px"><a-breadcrumb style="margin: 16px 0"><a-breadcrumb-item>Home</a-breadcrumb-item><a-breadcrumb-item>List</a-breadcrumb-item><a-breadcrumb-item>App</a-breadcrumb-item></a-breadcrumb><a-layout-content:style="{ background: '#fff', padding: '24px', margin: 0, minHeight: '280px' }">Content</a-layout-content></a-layout></a-layout></a-layout> </template><script>import {defineComponent} from 'vue'export default defineComponent({name: 'app',components: {}}); </script><style>#components-layout-demo-top-side-2 .logo {float: left;width: 120px;height: 31px;margin: 16px 24px 16px 0;background: rgba(255, 255, 255, 0.3);}.ant-row-rtl #components-layout-demo-top-side-2 .logo {float: right;margin: 16px 0 16px 24px;}.site-layout-background {background: #fff;} </style>
