webpack打包报错Unexpected token

　　最近项目要上线，需要对项目进行打包部署到服务器上面，在打包过程中npm run build后出现以下报错Unexpected token: punc (() [./~/[email protected]@element-ui/packages/col/src/col.js:23,0][static/js/0.3fbe30ed5a683f62d6bc.js:13890,10]

字面意思是报错来自UglifyJs，在col.js下23行出现了不期望的‘（’，打开col.js文件查看

不能识别这个函数的括号，上网查询后原来是UglifyJs不能解析ES6的问题，element-ui下的这个col文件使用了ES6的语法，所以导致无法解析，解决方法是在打包时，让babel去解析失败的包，打开webpack.base.conf.js,可以如下配置

然后再build一次，就大功告成。
