如何修复Node.js错误：找不到模块“沉浸式”

在此错误中，我无法运行npm start。我的用于运行后端服务器的脚本。下面显示的是我在package.json中的脚本。

  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject",
    "server": "nodemon server.js",
    "client": "npm run start --prefix client",
    "dev": "concurrently \"npm run server\" \"npm run client\""
  },

我从另一个stackoverflow帖子中看到了这个和这个，但是对我来说情况不一样。

我试图做npm安装并更新npm本身。在遇到错误之前，我正在安装和卸载npm软件包，所以我重置为旧的提交，因为也许package.json中的更改导致了该错误。完成此操作后，我仍然遇到相同的错误。有解决这个问题的想法吗？谢谢！

这是错误：
