废话不多说，直接上代码
注释掉 vue 和 antdv
Vue.use(antd); 这句话一定不能删除
antd 变量虽然没有定义，但是，是cdn资源里面的模块，一定要引入进来
如果提示 antd 未定义可能是 cdn 资源问题，
参考 : https://blog.csdn.net/qq_31254489/article/details/113097548
参考代码：
// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import App from './App'
// import Vue from 'vue'
// import antd from 'ant-design-vue';
// import 'ant-design-vue/dist/antd.css';
import router from './router'
Vue.config.productionTip = false
Vue.use(antd);
/* eslint-disable no-new */
new Vue({
el: '#app',
router,
components: { App },
template: '<App/>'
})
其实完全不需要修改 webpack 配置，网上一堆说使用 externals 的，其实不用，直接注释掉 import 就行了
引入3个cdn
