Question

我最近在heroku上部署了Rails应用程序，但是没有任何问题，现在，我正在尝试在heroku上部署Rails / react应用程序，这让我很费时间。有人可以帮我指出正确的方向吗？我为heroku添加了nodejs和ruby buildpacks。恐怕我缺少将两个环境连接在一起的功能。这是我当前遇到的错误，请多多关照。谢谢！

请参阅Heroku文章链接。

您可以找到Ruby detect script here。

您的项目与Ruby buildpack不兼容，因为它在git仓库的根目录中缺少Gemfile。

尝试部署Rails / React应用时，该应用与buildpack不兼容
