vue.config.js
module.exports = { configureWebpack:{ externals: { vue: ‘Vue‘, ‘vue-router‘:‘VueRouter‘, axios: ‘axios‘ } } }
在index.html文件中引入CDN
<!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width,initial-scale=1.0"> <link rel="icon" href="<%= BASE_URL %>favicon.ico"> <title></title> <link href="https://cdn.bootcss.com/element-ui/2.12.0/theme-chalk/index.css" rel="stylesheet"> <script src="https://cdn.bootcss.com/vue/2.6.10/vue.js"></script> <script src="https://cdn.bootcss.com/vue-router/3.1.3/vue-router.js"></script> <script src="https://cdn.bootcss.com/element-ui/2.12.0/index.js"></script> <script src="https://cdn.bootcss.com/element-ui/2.12.0/locale/zh-CN.js"></script> <script src="https://cdn.bootcss.com/axios/0.19.0-beta.1/axios.js"></script> </head> <body> <noscript> <strong>We‘re sorry but good doesn‘t work properly without JavaScript enabled.

在index.js文件中删除导入的elementui
import Vue from ‘vue‘ import App from ‘./App.vue‘ import router from ‘./router‘ //import ‘element-ui/lib/theme-chalk/index.css‘ //import ‘./plugins/element.js‘ import ‘./assets/global.css‘ Vue.config.productionTip = false new Vue({ router, render: h => h(App) }).$mount(‘#app‘)
