npm i element-ui -S

main.js中写入以下内容：

import Vue from 'vue';
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
import App from './App.vue';
Vue.use(ElementUI);
new Vue({
 el: '#app',
 render: h => h(App)
});

npm i vue-router@3.5.3

首先在src里面创建
router的目录，在router目录里面创建一个index.js文件
views目录 mian.vue

import Vue from 'vue'; //导入vue
import Router from 'vue-router'; /* 导入路由 */
import Login from '@/views/HelloWorld.vue'; /* 导入其他组件 */
import Main from '@/views/HelloWorld.vue'; 
Vue.use(Router)
/* 定义组件路由 */
var router = new Router({
	routes: [{
			path: '/', //ip:端口访问时 默认显示组件
			component: Login
		},
		{
			path: '/login', //组件地址
			component: Login
		},
		{
			path: '/main',
			component: Main
		}
 
	]
});
export default router

main.js

import Vue from 'vue'
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';

import router from './router/index.js'
import App from './App.vue'
Vue.use(ElementUI);
Vue.use(router)

Vue.config.productionTip = false

new Vue({
  render: h => h(App),
  router,
}).$mount('#app')

app.vue

<template>
  <div id="app">
    <!-- router-view就是用来显示不同组件的 -->
		<router-view></router-view>
  </div>
</template>

<script>
export default {
  name: 'App',
}
