【React】webpack打包之后运行报错,求帮忙解决或者提供个思路?
问题描述
在项目中引用一个npm包,打包后会报Super expression must either be null or a function错误,
但这个包在其他项目中引用没有问题
问题出现的环境背景及自己尝试过哪些方法
dev可以,打包过程没有报错,打包后执行js就会报出Super expression must either be null or a function。尝试过检查拼写问题、react版本。现在怀疑是存在循环引用的情况

你期待的结果是什么?实际看到的错误信息又是什么?
执行chunk.js后报错,希望大佬们给个思路或者解决方案
回答
我今天也遇到了这个问题,奇怪的是,我打包后的包,引入到我自己的项目里面正常到,我同事的项目中引人就报了这个错误。先打个TAG,后面有解决方案再来更新,作者解决了也请分享下 谢谢
