谁能帮我解决 npm --prefix 问题？

Question

我坚持使用 npm --prefix。 我正在尝试为我的前端文件夹添加前缀，以便我可以同时运行后端和前端。

我不断收到错误路径的错误消息：\backend\frontend/package.json。

任何人都可以帮我吗？

{
      "name": "backend",
      "version": "1.0.0",
      "description": "User Authentication APP - MERN stack",
      "main": "server.js",
      "scripts": {
        "start": "node backend/server.js",
        "server": "nodemon backend/server.js",
        "client": "npm start --prefix frontend ",
        "dev": "concurrently \"npm run server\" \"npm run client\""
      }
    }

Answer 1

You can test this package.json
 "scripts": {
    "server": "npm run watch --prefix server",
    "client": "npm start --prefix client",
    "watch": "npm run server & npm run client"
}

-> npm run watch
