在 Heroku 上部署 create-react-app 应用程序错误
Application Error Deploying create-react-app on Heroku
我在尝试在 Heroku 上部署一个非常基本的 React.js 应用程序时尝试了许多在线解决方案或修复此错误。当我 运行 git push heroku master 时，我的应用程序构建成功，但每次我尝试打开它时，我都会收到一个应用程序错误，日志如下：
2020-05-14T03:16:02.986304+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/favicon.ico" host=ravenous-react-application.herokuapp.com request_id=b4546431-d236-4c53-90de-cea6185c1d86 fwd="34.100.75.75" dyno= connect= service= status=503 bytes= protocol=https
据我了解，一切都应该正确设置。我的回购可以在这里找到 https://github.com/christulin/ravenousReactApp.
非常感谢任何帮助！
您的回答不正确procfile text file. See Define a Procfile。将内容从 web: node app.js 更改为 web: node server.js。
另外，你的代码导入的模块有路径问题，会导致构建失败。这是PR
