我已经构建了一个使用React和Mongo的完整堆栈应用程序。基本上在我的package.json中，我有这个脚本：
"scripts": {
"start": "node server.js & node src/server/index.js ",
},
其中server.js是使用webpack保存前端的地方，而t src/server/index.js是React从中获取数据的API数据库。
我已经尝试过部署，但由于脚本我收到了错误。
我已经部署了每个（一次一个）并且两者都有效。
有没有办法告诉Heroku同时运行两个脚本？
对于那些好奇的人来说，这是我的package.json

答案 0 :(得分：0)
这可能是因为PORT冲突，Heroku在单个PORT上运行“node server.js & node src/server/index.js”。
