【问题标题】:Application Error Deploying create-react-app on Heroku在 Heroku 上部署 create-react-app 的应用程序错误
【发布时间】:2020-05-14 03:36:26
【问题描述】:

在尝试在 Heroku 上部署一个非常基本的 React.js 应用程序时,我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并读取日志:

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。我的仓库可以在这里找到https://github.com/christulin/ravenousReactApp

任何帮助将不胜感激!

【问题讨论】:

  • 我最好的猜测是您缺少package.json 中的homepage 属性。尝试将"homepage": <your-heroku-app-url> 添加到您的package.json,然后构建和部署项目。
  • 刚刚添加无济于事,日志中仍然出现同样的错误..

【解决方案1】:

您的procfile 文本文件不正确。见Define a Procfile。将内容从web: node app.js 更改为web: node server.js

此外,您的代码导入的模块存在路径问题,这将导致构建失败。这是PR

    【解决方案2】:

    我通过安装 buildbpack https://github.com/mars/create-react-app-buildpack 以及添加带有此 web: bin/boot 的 procfile 来解决我的问题,希望它有所帮助。
