Node - Bind Node or Gulp to System Path

Common error in this case:

'gulp' is not recognized as an internal or external command, operable program or batch file.
Solution:

PATH=%PATH%;C:\Users\**<username>**\AppData\Roaming\npm

Node Sass could not find a binding for your current environment :

Solution:

> npm rebuild node-sass

First Time or If the project has added NPM run:

npm install

npm install gulp -g

Möjligen också installera yarn.

Kör Remember:

Vid Deploy: Skriv: yarn run build 

Vid Test: Skriv:  yarn run dev

NO gulp command found: If nothing works  reinstall nodejs and then reinstall with gulp. However gulp doesnt support the new nodejs so NVM needs to set older version.
