Question

我正在尝试使用create-react-app作为前端，express作为后端，使用concurrently软件包来建立一个项目，以使两个应用程序同时运行。但是，每次尝试从ELIFECYCLE开始时，我都会遇到错误npm run start，并且阅读日志并不能使我了解正在发生的事情。

有人可以帮我一下吗？

package.json

{
  "name": "demo",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "client": "cd client && npm start",
    "back-end": "cd back-end && npm start",
    "start": "concurrently --kill-others \"npm run back-end\" \"npm run client\""
  },
  "repository": {
    "type": "git",
    "url": "git+https://github.com/xyz/xyz.git"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "concurrently": "^4.1.0"
  }
}
