我制作了一个可与pyramida-graphql服务器一起使用的react应用程序。服务器位于react应用程序内部。我想用Heroku部署它（有史以来第一次使用它）。当我部署到Heroku时，运行heroku logs --tail

我在项目上使用的不是npm的yarn，有人知道我需要做些什么才能部署我的项目吗？因为我的项目未在heroku上运行，因为尝试打开已部署的版本时得到了此信息
Application error
An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. You can do this from the Heroku CLI with the command
heroku logs --tail
我认为问题是您正在尝试在heroku上启动React开发服务器。您的react应用应作为静态js捆绑包提供，该捆绑包是在运行生产版本cmd npm run build之后生成的。
仅查看此用例开发的https://github.com/mars/create-react-app-buildpack，并使其更加容易。
[如果您要部署整个堆栈...请查看详细介绍了它的post。
希望这会有所帮助！
