我正在尝试运行并发库，但我遇到了一些命令问题。我正在使用这个： https ://www.npmjs.com/package/concurrently

我在我的服务器上尝试更改 package.json：

 "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start":"node index.js",
    "server": "nodemon index.js",
    "client": "cd client && npm run serve",
    "dev": "concurrently \"nodemon index.js\" \"npm run serve\""
  },

我有 2 个单独的目录：服务器和客户端

在此处输入图像描述

当我尝试“npm run dev”时，我得到：

[0] [nodemon] 2.0.3
[0] [nodemon] to restart at any time, enter `rs`
[0] [nodemon] watching path(s): *.*
[0] [nodemon] watching extensions: js,mjs,json
[0] [nodemon] starting `node index.js`
[1] npm ERR! missing script: serve

服务可能是在客户端目录中定义的，因此您需要先 cd 那里。

"dev": "concurrently \"nodemon index.js\" \"cd client && npm run serve\""
