Dokku 上的 Create-react-app 部署失败

Question

我正在尝试部署通过 Create-react-app to my Dokku on DigitalOcean thank to this heroku buildpacks 制作的全新 React 应用程序。按照他们的指示，最终失败了...

似乎一切正常，但应用程序从未启动。我在这里错过了什么？

Answer 1

解决方案相当简单。整个构建工作正常，但必须以某种方式初始化应用程序。

我添加了一个Procfile并在里面写了下面一行...

web: npm start

希望对您有所帮助。

Answer 2

因为我有同样的问题，所以我为这个特定的构建包打开了一个问题：https://github.com/mars/create-react-app-buildpack/issues/54 幸运的是它的维护者非常友好地为我提供了正确的 Procfile 内容。

要解决此问题，您应该有一个 Procfile，其中包含以下行：

web: bin/boot

而不是 web: npm start 这不会生成完整的开发服务器。因此，您的服务器 memory/cpu 使用起来应该容易得多。
