错误：找不到绑定文件。试过：（Webpack）

Question

我正在创建这个使用 npm 包 natural 的小项目，当我使用 webpack 捆绑代码时，我收到了这些警告。

yarn run v0.18.1
$ webpack

当我运行捆绑代码时，出现以下错误。

/Users/jakelacey/proj/ai/blankitv.0.0.1/dist/bundle.js:7860
    if (e.code !== 'MODULE_NOT_FOUND') throw e;

应用程序的代码是

var natural = require('natural');
var classifier = new natural.BayesClassifier();

// train.. 
classifier.addDocument('What is qqqq', ['question', 'unidentified']);
classifier.addDocument('can you give me an example of qqqq', ['example', 'maths', 'multiplicatication']);
classifier.addDocument('what is multiplication?', ['question', 'maths', 'multiplicatication']);
classifier.addDocument('addition', ['maths', 'addition']);
classifier.addDocument('division', ['maths', 'division']);

classifier.train();

console.log(classifier.classify('what is multiplication'));
console.log(classifier.classify('what is english'));
console.log(classifier.classify('what is english'));
console.log(classifier.classify('can you give me an example of multiplication'));

webpack 配置是这样的，

var path = require('path');
var FlowTypePlugin = require('flowtype-loader/plugin');

module.exports = {

  target: 'node',

  entry: './src/index.js',

  output: {
    filename: 'bundle.js',
    path: path.resolve(__dirname, 'dist')
  },

  module: {
    rules: [
      { 
        test: /\.js$/,
        exclude: /node_modules/,
        use: [
          {
            loader: 'flowtype-loader',
          },
          {
            loader: 'babel-loader',  
          }
        ]
      }
    ]
  },

  plugins: [
    new FlowTypePlugin()
  ]

}

有人大致了解这里发生了什么吗？提前谢谢你。

您在运行 npm install 时是否遇到错误（尤其是在安装包 node-webworker-threads 的本机组件时，我认为您正在使用它）？您是否为您的开发平台安装了原生构建工具链（包括 C 编译器）？
