问题描述
iview admin项目npm run build 打包时UglifyJs报错（ERROR in 1.2db93f96dd466683d093.chunk.js from UglifyJs Unexpected token: operator (>) [1.2db93f96dd466683d093.chunk.js:46439,43]）
问题出现的环境背景及自己尝试过哪些方法
在打包后的文件1.2db93f96dd466683d093.chunk.js查看>应该识别错误，分析有可能是因为UglifyJs对es6语法解析转义出现了问题，在网上寻找了一些配置更改的方法还是无效，请大家帮忙看看，有什么方法可以解决。

踩了一天这个坑，终于跳出来了，根据自己的webpack.base.config.js所在的目录，打包的时候相应的include需要babel的路径，路径一定要正确，且include 和 exclude不能共用，或者说不能同时作用于同一个目录吧。
按正常的逻辑。node_modules 里的文件应该不包含es6的代码才对
