我正在开发一个 React 应用程序，我无法在 Safari 和 IE 中打开这个应用程序。

对于 IE-11： SCRIPT1028: SCRIPT1028: Expected identifier, string or number

如果需要更多详细信息，请告诉我。

请建议，我需要做什么....谢谢

我的webpack.js文件是......

const path = require('path');
const HtmlWebPackPlugin = require('html-webpack-plugin');
const {
  CheckerPlugin,
  TsConfigPathsPlugin,
} = require('awesome-typescript-loader');
const DuplicatePackageCheckerPlugin = require('duplicate-package-checker-webpack-plugin');

const ROOT = path.resolve(__dirname, '..');

module.exports = {
  module: {
    rules: [
      {
        test: /.tsx?$/,
        use: 'awesome-typescript-loader',
        exclude: /node_modules/,
      },
      {
        test: /.(png|jpg|gif|svg)$/,
        use: [
          {
            loader: 'url-loader',
            options: {
              limit: 25000,
            },
          },
        ],
      },
      {
        test: /.html$/,
        use: 'html-loader',
      },
    ],
  },
  resolve: {
    extensions: ['.tsx', '.ts', '.js'],
    modules: [path.resolve(ROOT, 'shared'), 'node_modules'],
    plugins: [new TsConfigPathsPlugin()],
  },
  plugins: [
    new HtmlWebPackPlugin({
      template: path.join(ROOT, 'shared', 'index.html'),
      filename: './index.html',
    }),
    new CheckerPlugin(),
    new DuplicatePackageCheckerPlugin(),
  ],
};

我认为babel-loader可以工作，但找不到任何使用 babel-loader 的方法。

请提出一些解决方案...

问题是默认情况下，应用程序在 IE7 上呈现，而不仅仅是在支持转译构建的 IE IE11/EDGE 上。 所以我不得不提到元信息让浏览器知道预期的浏览器是 IE11/edge。 在 index.html 的头部添加这个：

现在您可能会在控制台中出现以下错误：

SCRIPT5009：“设置”未定义
