在 heroku "Failed to minify the code from this file" 上反应应用程序部署失败

Question

我使用 create-react-app 命令创建了一个反应应用程序，并尝试按照 https://github.com/mars/create-react-app-buildpack#quick-start 上的说明将其部署到 heroku 上

但是，在尝试推送到 heroku 时，我想出了以下构建失败，其中构建日志读取：

Creating an optimized production build...

newsapi/index.js在第17行读到：

let API_KEY; // To be set by clients

Answer 1

如果不看到newsapi/index.js，很难说错误可能是什么。该文件可能包含不支持或无法缩小的语法。一种解决方案是查看该行是否为导入，并创建该依赖项的本地版本，并删除或更新有问题的语法。
