Nodemon 不启动服务器

Question

I installed nodemon to devDependencies and set the script "start": "nodemon server.js" . However, when I do npm start , it throws me this error:

Error: Cannot find module 'C:\Users\win10\Desktop\nodemon\bin\nodemon.js'
    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:880:15)

npm ERR! Exit status 1

npm ERR! Failed at the question-answer-rest-api@1.0.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

My package.json

{
  "name": "question-answer-rest-api",
  "version": "1.0.0",
  "description": "Back end project for practice",
  "main": "server.js",
  "scripts": {
    "start": "nodemon server.js"
  },
  "keywords": [
    "Express",
    "Nodejs",
    "Mongoose",
    "Api"
  ],
  "author": "Cihan Özcan",
  "license": "MIT",
  "dependencies": {
    "express": "^4.17.1"
  },
  "devDependencies": {
    "nodemon": "^2.0.7"
  }
}

I also filled in server.js and tried that way but it didn't work.

My server.js file

const express = require('express');

const app = express();

const PORT = 5000

app.listen(PORT, () => {
    console.log(`Server started on port ${PORT}`)
})

There are no any file in the folder. I couldn't find similar error in SO. I installed nodemon as global and checked the global environment in pc. There is no problem with it.

What is the problem?

Answer 1

Try

npm uninstall nodemon

Then

npm install -g nodemon

It should works
