ERR! code ENOENT in Windows 10 when using npm run watch

Hey everybody

After following all the steps of the Starter-Kit-2018 and Installing all the node packages, gulp -v, and webpack -v, from the Dev-Starter-Kit...

When i try to Start the server

npm run watch,

it's still giving me a ERROR...

C:\Users\mondc>npm run watch

I read all others issues but i did not find any solution.

I'll appreciate any HELP... PLEASE...
