Babel 7将ES6 node_module转换为ES5不起作用

我无法理解为什么这不起作用。也许我在看医生时太草率了。在我的webpack项目中,我无法通过babel将ES6 node_module(ol aka openlayers)转换为es5。我正在使用 babel.config.js 正如babel在这个案例中所建议的那样。

运行后 webpack build 这个 main.js bundle仍然具有类似箭头函数的ES6代码 const 和 let 。

如何转换 ol 通过babel 7封装到es5?

//babel.config.js
const path = require('path')

module.exports = {
  presets: [
    '@babel/preset-react',
    [
      '@babel/preset-env',
      {
        targets: {
          browsers: 'IE 11, not dead'
        },
        useBuiltIns: 'entry',
        corejs: {
          version: '3',
          proposals: true
        }
      }
    ]
  ],
  plugins: [
    '@babel/plugin-transform-runtime',
    '@babel/plugin-transform-modules-commonjs',
    ['styled-components', { ssr: true }]
  ],
  exclude: [
    /\bcore-js\b/,
    /\bwebpack\/buildin\b/,
    /\node_modules\/(?!(ol)\/).*/
  ]

}

//webpack.config.js
const path = require('path')
const HtmlWebpackPlugin = require('html-webpack-plugin')
