构建时发生错误：vendors.js：21未捕获的TypeError：超级表达式必须为null或函数，且未定义

Question

因此，在构建用于生产的代码时，webpack出现了问题（此错误仅在为prod进行构建时附加，而在将webpack与devServer一起使用时不会附加）。

这是错误：

vendors.js:21 Uncaught TypeError: Super expression must either be null or a function, not undefined

（例如，在使用http-server启动构建的项目后，此错误出现在浏览器的控制台中）

我不认为此错误是由于我的webpack配置所致，因为我在许多其他项目中都使用了此配置，并且从未遇到过问题。

但是我留给你（以防万一）：

const path = require('path');

const UglifyJsPlugin = require('uglifyjs-webpack-plugin');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');
const OptimizeCSSAssetsPlugin = require('optimize-css-assets-webpack-plugin');
const HtmlWebPackPlugin = require('html-webpack-plugin');
const TerserPlugin = require('terser-webpack-plugin');

const host = 'localhost';
const port = 3000;

const devMode = process.env.NODE_ENV !== 'production';

module.exports = {
  mode: 'development',
  resolve: {
    alias: {
      src: path.resolve(__dirname, 'src/')
    }
  },

    ]
  },
  // Outputs
  output: {
    filename: 'app.js',
    chunkFilename: 'vendors.js',
    path: path.resolve(__dirname, 'dist'),
    publicPath: '/'
  },
  optimization: {
    splitChunks: {
      chunks: 'all'
    },
    minimizer: [
      new TerserPlugin(),
      new UglifyJsPlugin({
        cache: true,

      }),
      new OptimizeCSSAssetsPlugin({})
    ]

            loader: 'babel-loader',
            options: {
              cacheDirectory: true
            }
          }
        ]
      },
      // CSS / SASS / SCSS
      {
        test: /\.(sa|sc|c)ss$/,
        use: [
          devMode ? 'style-loader' : MiniCssExtractPlugin.loader,
          'css-loader',
          {
            loader: 'postcss-loader',
            options: {
              plugins: () => [require('autoprefixer')],
              sourceMap: true
            }
          },
          // SASS
          'sass-loader'
        ]
      },
      // Inages
      {
        test: /\.(png|svg|jpg|gif|eot|woff|woff2|ttf)$/,
        use: [

            loader: 'file-loader',
            options: {
              outputPath: 'assets/'
            }
          }
        ]
      }
    ]
  },
  devServer: {
    overlay: true,
    stats: 'minimal',
    progress: true,
    inline: true,
    open: true,
    historyApiFallback: true,
    host: host,
    port: port
  },
  plugins: [
    new HtmlWebPackPlugin({
      template: './src/index.html',
      filename: './index.html'
    }),
    new MiniCssExtractPlugin({
      filename: '[name].css',
      chunkFilename: '[id].css'
    })
  ]
};

我确实认为（但我可能错了），问题出在我的依赖项上（可能是多个包之间的冲突）：

是的，在我的webpack配置中有一些打字稿依赖关系，但没有任何支持。这是因为我在此项目中部分使用了打字稿，但问题并非出自这里。我删除了webpack配置和项目中的所有ts集成，问题仍然存在。

我正在使用yarn，因此我尝试删除了yarn.lock文件，但没有帮助。

此错误并非来自我的代码。我只测试了其中带有h1的一个组件，但不能解决问题。
