Javascript NPM模块导致web应用程序无法在IE11上呈现

所以我使用的是我同事在npm上发布的react组件。它在除IE11之外的所有浏览器上都可以正常工作。我怀疑网页包配置中有我们忽略的东西导致整个应用程序无法呈现。没有错误消息，只有一个空白网页

src/index.js文件如下所示：

Class MuiTable extends Component {
...
}
export default compose(withStyles(styles, { withTheme: true }(MuiTable);

以下是webpack.config.js文件：

var path = require('path');
module.exports = {
  entry: './src/index.js',
  output: {
    path: path.resolve(__dirname, 'build'),
    filename: 'index.js',
    libraryTarget: 'commonjs2'
  },
  module: {
    rules: [
      {
        test: /\.js$/,
        include: path.resolve(__dirname, 'src'),
        exclude: /(node_modules|bower_components|build)/,
        use: {
          loader: 'babel-loader',
          options: {
            presets: ['env']
          }
        }
      }
    ]
  },
  externals: {
    'react': 'commonjs react'
  }
};

以下是.bablerc：

{
  "presets": ["env"],
  "plugins": [
    "transform-object-rest-spread",
    "transform-react-jsx"
  ]
}

下面是package.json：

为什么这不适用于IE11？

您可能需要引用polyfills.js以使其适用于IE

您可以使用这些导入引用polyfills.js：

/* polyfills.js */

import 'core-js/fn/array/find';
import 'core-js/fn/array/includes';
import 'core-js/fn/number/is-nan';

确保您执行了

npm安装core js
