• Laravel Version: 5.7
• PHP Version: PHP 7.2.10
• Database Driver & Version: MySQL: mysql Ver 14.14 Distrib 5.7.24

When running npm run watch, I get the following error:

@laidbackwebsage
Can you please try:

• npm cache clean --force
• rm -rf node_modules
• npm install
• npm run dev
• npm run watch

Also what are your npm and node versions?

[laidbackwebsage]

$ node -v
v8.12.0
$ npm -v
6.4.1

This worked, thank you very much!

My environment is;

---

1. Win-7 x64
2. PHP 7.1
3. Laravel 5.8

1. I tried installing node.js from; https://nodejs.org/download/release/v10.14.2/
2. Then check the version of node.js in cmd prompt, c:\Users\admin> node -v
3. Then it comes to npm installation I tried installing from npm site https://www.npmjs.com/get-npm,
   copy the npm install npm@latest -g
4. Then check the version using cmd prompt: c:\Users\admin> npm -v

after these steps,
I tried this command c:\xampp\htdocs\laravel> npm run watch (worked for me)

thank you
Let me know if it worked !!!
