NPM while starting it shows Cannot find module 'safe-buffer'

Question

I am trying to create a Node Restful API service, but npm is giving me an error while starting. In command prompt I have typed the following :

D:\xampp\htdocs\todoListApi>npm run start

todolistapi@1.0.0 start D:\xampp\htdocs\todoListApi

nodemon server.js

It shows following error

[nodemon] 1.17.3
[nodemon] to restart at any time, enter `rs`
[nodemon] watching: *.*
[nodemon] starting `node server.js`
internal/modules/cjs/loader.js:550
    throw err;
    ^

Instead it should start npm and show result as

todo list RESTful API server started on: 3000

Please guide me on how I can overcome this.

Try using ``npm cache clean --force `` and if it still doesn't work, try to fully re-install NPM — HRK44, Apr 20 '18 at 12:02
Uninstall node and removed npm and npm-cache folder manually in User->appdata directory and its worked — Kashyap Patel, Apr 20 '18 at 13:21

The following steps worked for me :

Uninstall Node.js from Control Panel
Go C:/Users/Admin/AppData/Roaming
Delete npm and npm-cache manually

Try installing node.js again.

Try using npm cache clean --force and if it still doesn't work, try to fully re-install NPM/Node :)
