我有prod构建的问题。我部署它时一切都很好，我可以访问该网站，但两个页面给我一个TypeError：r不是一个函数。我一直在github和其他网站上查看很多问题，但是没有找到任何有用的东西。 Here is the error (image)
我正在使用webpack 3.10.0，babel 6.23.0，节点8.9
这是webpack.config.js

所以，我向后退了一步，看到了我的错误。我使用UglyfyJS来减少生产部署中js文件的大小，并没有注意到，当前版本不能与TS语言竞争，因此，在我的情况下，正确的做法是安装UglyfyJS和谐并删除babel-loader 。之后，当我导入所有东西时，它开始运作良好。
