Question

我正在关注 this YouTube教程系列，但是突然在运行服务器时遇到了这个问题我尝试将节点重新卸载到最新的稳定版本。

internal/modules/cjs/loader.js:968
  throw err;
  ^

Error: Cannot find module 'D:\DATA\Learning\Creations\WEB\website\tabs tracker\Vue-and-Express.JS\server\scr\app.js'
    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:965:15)

    at internal/main/run_main_module.js:17:47 {
  code: 'MODULE_NOT_FOUND',
  requireStack: []
}

app.js代码

const express = require('express')
const bodyParser = require('body-parser')
const morgan = require('morgan')
const cors = require('cors')
const { sequelize } = require('./models')
const config = require('./config/config')

const app = express()

app.use(morgan('combined'))
app.use(bodyParser.json())
app.use(cors())

require('./routes')(app)

sequelize.sync().then(() => {
  app.listen(config.port)
  console.log(`Serverstarted on port ${config.port}`)
})

Answer 1

我认为您在代码中的某个地方输入了'app'而不是/scr/app

时出现错字

Answer 2

将scr/app.js中的src/app.js更改为package.json

Answer 3

在使用 #vuejs 时遇到这个问题，我的解决方法是删除 package.lock.json 文件和 node_modules 文件夹。然后我运行 npm i 然后 npm run serve 运行良好

错误：internal / modules / cjs / loader.js：968 throw err;节点模块？
