npm install -g @angular/cli should have been sudo npm install -g @angular/cli ?

WARN engine @angular/cli@1.2.1: wanted: {"node":">= 6.9.0","npm":">= 3.0.0"} (current: {"node":"4.2.6","npm":"3.5.2"})

Looks like you've got node v4.2.6 installed. AngularCLI requires >= 6.9.0. Go to https://nodejs.org/en/ and download the latest version.

but F**** linux shitty mint installed that old version !!

A simple way to upgrade Node.js from the Terminal is to use the n version manager:

1. 1 npm install -g n 2 npm cache clean -f.
2. 1 cd /Applications/XAMPP/xamppfiles/bin 2 sudo mv HEAD _HEAD.
3. 1 sudo n stable 2 npm update -g.
4. 1 cd /Applications/XAMPP/xamppfiles/bin 2 sudo mv _HEAD HEAD.
5. 1 node -v 2 npm -v

this is what google gives me as an answer. I dont F** have xampp
