配置对象无效。Webpack 已使用与 API 模式不匹配的配置对象进行初始化。- 配置具有未知属性“模块”。这些属性是有效的:object { mode?, amd?, bail?, cache?, context?, dependencies?, devServer?, devtool?, entry?, externals?, loader?, module?, name?, node?, output ?,优化?,并行?,性能?,插件?,配置文件?,recordsInputPath?,recordsOutputPath?,recordsPath?,resolve?,resolveLoader?,stats?,target?,watch?,watchOptions?} 对于错别字:请更正。对于加载器选项:webpack >= v2.0.0 不再允许配置中的自定义属性。应该更新加载器以允许通过 module.rules 中的加载器选项传递选项。
