UglifyJs在其中一个node_modules文件中抛出意外令牌：punc«，»

Question

我正在使用@shopify/polaris软件包，它似乎导致我的构建失败并显示以下错误消息：

来自UglifyJs的vendor.file.bundle.js中的

错误意外 令牌：punc«，»[./node_modules/@shopify/polaris/index.es.js:1043,0]

当我在第1043行中检查./node_modules/@shopify/polaris/index.es.js文件时，似乎抱怨以下内容：

console.warn(i18n.translate('Polaris.Icon.backdropWarning', {
    color, // It seems to complain about this on line 1043.
    colorsWithBackDrops: COLORS_WITH_BACKDROPS.join(', ')
}));

我正在使用webpack4。以下是我的配置：

const path = require('path');

const config = {
  entry: './src/index.tsx',
  output: {
    path: path.resolve(__dirname, '/public/js'),
    filename: 'file.bundle.js',
    chunkFilename: 'vendor.file.bundle.js'
  },
  resolve: {
    extensions: ['.js', '.json', '.ts', '.tsx', '.css', '.scss'],
  },
  module: {
    rules: [
      {
        test: /\.s[ac]ss$/i,
        use: [
          // Creates `style` nodes from JS strings
          'style-loader',
          // Translates CSS into CommonJS
          'css-loader',
          // Compiles Sass to CSS
          'sass-loader',
        ],
      },
      { 
        test: /\.tsx?$/, 
        loader: 'babel-loader',
        exclude: /node_modules/
      },
      { 
        test: /\.js?$/, 
        loader: 'babel-loader',
        exclude: /node_modules/
      }
    ]
  },
  optimization: {
    splitChunks: {
      cacheGroups: {
        commons: {
          test: /[\\/]node_modules[\\/]/,
          name: 'vendor',
          chunks: 'initial',
          enforce: true
        }
      }
    }
  },
  {
    mode: 'production',
    plugins: [
        new UglifyJsPlugin({
            sourceMap: true
        }),
        new webpackProd.DefinePlugin({
            'process.env.NODE_ENV': JSON.stringify('production')
        }),
        new CompressionPlugin({
            filename: "[path].gz[query]",
            algorithm: "gzip",
            test: /\.js$|\.ts$/,
            threshold: 10240,
            minRatio: 0.8
        }),
        new webpackProd.IgnorePlugin(/^\.\/locale$/, /moment$/),
    ]
  }
};

module.exports = config;
