添加 IE 兼容

之前的方式会报 @babel/polyfill is deprecated. Please, use required parts of core-js and regenerator-runtime/runtime separately

@babel/polyfill 废弃，使用 core-js 和 regenerator-runtime

bash

npm i --save core-js regenerator-runtime

在 main.js 中添加

javascript

// 兼容 IE
// https://github.com/zloirock/core-js/blob/master/docs/2019-03-19-core-js-3-babel-and-a-look-into-the-future.md#babelpolyfill
import "core-js/stable";
import "regenerator-runtime/runtime";

配置 babel.config.js

javascript

const plugins = [];

module.exports = {
  presets: [
    ["@vue/cli-plugin-babel/preset", { useBuiltIns: "usage", corejs: 3 }],
  ],
  plugins,
};
