HappyPack报错，提示：HappyPack: unable to locate the plugin list ？

Question

vuecli3.0创建的项目

配置了一些webpack的优化方案，其中就有用到一个叫HappyPack的插件，用来并发打包项目。但是配置完之后打包过程中报错。

报错信息：

Module build failed (from ./node_modules/_thread-loader@2.1.2@thread-loader/dist/cjs.js):
Thread Loader (Worker 0)
HappyPack: unable to locate the plugin list! This most likely indicates an internal error.
