Start from installation from Node.js website ( if you use Windows or OS X ).

For Linux: $ sudo apt-get update $ sudo apt-get install nodejs

Then install the Node package manager called “npm”: $ sudo apt-get install npm

Create a symbolic link for “node” as many Node.js tools use this name to execute: $ sudo ln -s /usr/bin/nodejs /usr/bin/node

Install Gulp from the terminal: $ npm install --global gulp

Use $ npm install with no args, and this command will install the dependencies from a package.json manifest to the local node_modules folder.

Run gulp commands: $ gulp build - build all files from app to public;
