如何解决为什么Babel 7 Core-js @ 3在IE11中不起作用

babel依赖

{
    "@babel/cli": "7.10.5","@babel/core": "7.10.5","@babel/polyfill": "7.10.4","@babel/preset-env": "7.10.4","@babel/preset-react": "7.10.4","@babel/register": "7.10.5","babel-core": "7.0.0-bridge.0","babel-loader": "8.1.0",}

babelrc

{
  "presets": [
    [
      "@babel/preset-env",{
        "targets": {
          "node": "current","browsers": "since 2012"
        },"corejs": { "version": 3,"proposals": true },"useBuiltIns": "usage"
      }
    ],"@lingui/babel-preset-js","@babel/preset-react","@lingui/babel-preset-react"
  ],}

webpack

module.exports = {
  mode: 'production',entry: {
    applyWeb: path.join(paths.src.applyWeb,'index.js'),common: ['moment'],},module: {
    rules: [
      {
        test: /\.js$/,exclude: [path.resolve(__dirname,'node_modules'),path.resolve(__dirname,'src/lingui')],loaders: [
          threadLoaderOption,{
            loader: 'babel-loader',options: {
              cacheDirectory: `node_modules/.cache/babel-loader/${envHash}`,],...
};

来自babel网站

对于webpack，有多种方法可以包含polyfill：

与@ babel / preset-env一起使用时，

如果useBuiltIns：在.babelrc中指定了'usage'，则在webpack.config.js条目数组或源文件中都不要包含@ babel / polyfill。注意，仍需要安装@ babel / polyfill。

但是在IE11中，polyfill未按预期包含。
