我正在尝试使用dokku在数字海洋飞沫上部署create-react-app。我以前的部署已经成功完成，但是此应用最终失败了。请帮助我解决问题。下面是我的package.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

注意：-我在dokku日志中注意到我说“正在启动开发服务器...。”是否表示它仍以开发模式部署或我做错了什么？
答案 0 :(得分：1)
在降级为“反应脚本”：“ 3.4.0”之后，我终于解决了该问题。是的！
