我正在尝试运行节点服务器.js但被告知错误：找不到模块"C：\用户\用户\OneDrive\桌面\节点\后端\服务器.js

每当我运行node server.js时，我都会得到上述错误，我已经多次运行NPM安装，但所有这些都是徒劳的

const express = require("express")
var app = express()
const port = 3000
app.get('/', (_req, res) =>{
res.send('Hello World')
})
app.listen(port, ()=>{
console.log(`server is running on port number ${port}`)
})

我期望终端控制台服务器在端口号3000上运行我安装了express，但我被告知MODULE NOT FOUND

您的代码看起来很好，应该运行，假设您之前使用了例如npm init -y和npm install express。我想npm start给你同样的错误?

除此之外，似乎你的代码是在与OneDrive同步的文件夹中…你确定它是正确同步的吗?您是否尝试过显示server.js的内容，例如more server.js?
