我在学习MERN堆栈。我正在学习这个教程：https://www.youtube.com/watch?v=ngc9gnGgUdA&t=941s
基本上，当我运行“npm start”时，它不会读取我的index.js。我下面的教程是新鲜和高度评价。但是我在教程的早期就被卡住了，错误信息并不是真的隐含的。15分钟后卡住了。
我将非常感谢关于这个主题的一些信息/指导。
我的脚步，直到我开始：

mkdir服务器
光盘服务器

npm init -y**

npm install body-parser cors express mongoose nodemon
code package.json

{
  "name": "server",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "type": "module",
  "scripts": {
    "start": "nodemon index.js"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "body-parser": "^1.19.0",
    "cors": "^2.8.5",
    "express": "^4.17.1",
    "mongoose": "^5.13.7",
    "nodemon": "^2.0.12"
  }
}

字符串

code index.js

console.log('Why I cant read this file ?')

import express from 'express';
import bodyParser from 'body-parser';
import mongoose from 'mongoose';
import cors from 'cors';

现在运行npm start，得到错误
