解决方案

如果您想同时运行前端（React）和后端（Node），请同时安装和 nodemon。

npm i concurrently 
npm install -g nodemon

然后在 package.json 文件中同时添加以同时运行前端和后端。

"scripts": {
    "start": "node server/index.js",
    "backend": "nodemon server/index.js",
    "frontend": "npm run start --prefix client",
    "dev": "concurrently \"npm run backend\" \"npm run start --prefix client\""
  },

如果您只想运行前端，请转到客户端文件夹并打开终端并键入

npm start or yarn start
