我正在尝试使用dokku在数字海洋水滴上部署create-react-app。我在以前的部署中取得了成功，但是这个应用程序终于失败了。请帮助我解决问题。下面是我的包.json文件和dokku日志

The project was built assuming it is hosted at /.
You can control this with the homepage field in your package.json.
The build folder is ready to be deployed.
You may serve it with a static server:
npm install -g serve
serve -s build

在降级到"反应脚本"后，我终于解决了这个问题："3.4.0"。是的！！
