Heroku 崩溃错误：heroku[router]：at=错误代码=H10 desc= "App crashed"方法=GET 路径= "/favicon.ico"

Question

我正试图在heroku上启动我的nodejs应用程序。但每次它启动时都会崩溃，并出现以下错误。人们不断提到我必须进行一些端口修复，但我不明白在哪里以及如何进行？有人能帮我调试这个崩溃问题吗。。如果我使用npm start在本地运行它，它工作得很好。

Heroku在每次dyno启动时随机分配的端口上运行。你有三个选择：

• 使用Heroku Buildpack进行零配置react应用程序：https://elements.heroku.com/buildpacks/mars/create-react-app-buildpack
• 使用Expresshttps://medium.com/better-programming/how-to-deploy-your-react-app-to-heroku-aedc28b218ae
• 使用其他手动设置端口的方法。这可能会有所帮助：在Heroku上为node.js服务器设置端口
