node.js - 无法同时启动客户端和服务器

Question

index.js： const port = process.env.PORT || 3000;

服务器包.json：

    "start": "node index.js",
    "server": "nodemon index.js",
    "client": "npm start --prefix client",
    "dev": "concurrently \"npm run server\" \"npm run client\""
  },

客户端包.json：

"proxy": "http://localhost:5000",

我开始npm run dev

知道问题可能出在哪里吗？

错误：

Error: Cannot find module '.../index.js'

Answer 1

尝试映射客户端项目的子路径：

{
    "start": "node index.js",
    "server": "nodemon index.js",
    "client": "cd client && npm start",
    "dev": "concurrently \"npm run server\" \"npm run client\""
},

Answer 2

因为我有应用程序和服务器文件夹，所以出现了同样的问题。我通过给出路径解决了这个问题 --> "application": "cd ../ && npm start --prefix application"

{
  "server": "nodemon server/app.js",
  "application": "cd ../ && npm start --prefix application",
  "dev": "concurrently \"npm run server\"  \"npm run application\" "
}
