Error in adding concurrently in package.json

Question

scripts in package.json

"scripts": {
    "start": "node back-end/server.js",
    "server": "nodemon back-end/server.js",
    "client": "npm start --prefix front-end",
    "dev": "concurrently \"npm run server\" \"npm run client\"",
    "test": "echo \"Error: no test specified\" && exit 1"
  },

whenever I run the code using concurrently it shows me error like this

$ npm run dev

> concurrently "npm run server" "npm run client"

[0] Error occurred when executing command: npm run server

尝试将"dev": "concurrently \\"npm run server\\" \\"npm run client\\"",替换为

"dev": "npm run server && npm run client",
