Webpack 2 - 'Debug'出错

Question

从webpack 1升级到webpack 2.运行时出错...

WebpackOptionsValidationError：无效的配置对象。 Webpack已使用与API架构不匹配的配置对象进行初始化。 - 配置具有未知属性'debug'。这些属性是有效的：

我已经为web pack.config.js文件包含了我的代码。

非常感谢有关此问题的任何帮助。

这是一个迁移指南，查找它声明已在loaderoptionsplugin下移动的调试属性

plugins: [ new webpack.LoaderOptionsPlugin({ debug: true }) ]

附注：如果要迁移到版本2，为什么不升级到版本4？
