我可以看到你的 package.json 中有“开始”脚本

  "scripts": {
    "start": "react-scripts start", <--- here
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },

react-scripts 是一组来自 create-react-app 入门包的脚本。

您需要npm start在终端中运行命令才能运行该应用程序。

在常见的应用程序中，启动脚本如下所示：

"start": "npx node index.js"

其中 index.js 也可以是 server.js 文件
