我使用HappyPack加快生产环境搭建速度，遇到问题，项目环境是vue-cli 4.0和webpack 4.0+，当我尝试使用命令'npm run build'构建项目时，它返回错误如下：

Syntax Error: Thread Loader (Worker 0)
HappyPack: unable to locate the plugin list! This most likely indicates an internal error.

我的配置文件“vue.config.js”看起来像：

const SpeedMeasurePlugin = require("speed-measure-webpack-plugin");
const HardSourceWebpackPlugin = require('hard-source-webpack-plugin')
const smp = new SpeedMeasurePlugin();

const HappyPack = require('happypack');
const os = require('os');
const happyThreadPool = HappyPack.ThreadPool({ size: os.cpus().length });

module.exports = {
  runtimeCompiler: true,
  productionSourceMap: false,
  configureWebpack: smp.wrap(config => {
      if (process.env.NODE_ENV === 'production') {
        return {
          module: {
            rules: [
              {
                test: /\.js$/,
                loader: 'happypack/loader?id=happyBabel',
                exclude: /node_modules/
              },
            ]
          },
          plugins: [
            new HardSourceWebpackPlugin(),
            new HappyPack({
              id: 'happyBabel',
              loaders: [{
                loader: 'thread-loader',
              }, {
                loader: 'babel-loader?cacheDirectory=true',
              }],
              threadPool: happyThreadPool,
              verbose: true,
            })
          ]
        }
      } else {
        return {
          module: {
            rules: [
              {
                test: /\.js$/,
                loader: 'happypack/loader?id=happyBabel',
                exclude: /node_modules/
              },
            ]
          },
          plugins: [
            new HappyPack({
              id: 'happyBabel',
              loaders: [{
                loader: 'thread-loader',
              }, {
                loader: 'babel-loader?cacheDirectory=true',
              }],
              threadPool: happyThreadPool,
              verbose: true,
            })
          ],
        }
      }
  }),
};

我不知道为什么它会抛出错误，它在开发模式下工作。请提供有关此问题的任何线程，谢谢您的帮助！
