Webpack 4.0内部版本“ {required is not defined”错误

Question

-已解决-我认为是通过重命名.babelrc使其不会被拾取... 仅包含在下面的配置规则中的babel的“ loader”和babel的“ preset”就足够了。我有从gulp构建中遗留下来的.babelrc ...当它被删除时，需求问题消失了...这个webpack很奇怪......

该错误发生在通过CLI上的“ heroku local”运行的localhost中，因此该应用程序是从./dist托管的。 2张照片显示了devtools中的错误照片。我不知道其中一个衬里含有：

module.exports = require("path");  

来自，但是代码扫描仅在script标签中加载的库中显示包含此类需求的js文件。

没有成功，尝试在配置中进行许多排列以尝试删除有问题的'require'语句，但无济于事：

 externals: /^.*\.min\.js$/i,

    { test: [/app\/scripts\/encoderWorker\.min\.js/,
      /app\/scripts\/decoderWorker\.min\.js/],

        parser: {
          amd: false, // disable AMD
          commonjs: false, // disable CommonJS
          system: false, // disable SystemJS
          harmony: false, // disable ES2015 Harmony import/export
       requireInclude: false, // disable require.include
       requireEnsure: false, // disable require.ensure
       requireContext: false, // disable require.context
       browserify: false, // disable special handling of Browserify bundles
       requireJs: false, // disable requirejs.*
       node: false, // disable __dirname, __filename, module, require.extensions, require.main, etc.
     }

      }


    noParse:  /app\/scripts\/encoderWorker\.min\.js/,

  externals: [nodeExternals()],

我已经转储了清单文件，并从构建中查看了stdout，但是唯一值得注意的是stdout始终包括：

 42 B     path             external "path"                                                  built

这将导致错误。为什么会生成？似乎是越野车...
