Hello !
since I have troubles with “npm install”, I have completely uninstall Node.js and reinstall it from scratch.
after this I executed the following command on my theme directory sudo npm install -g bower gulp
But now when I try to execute gulp I have the following mistake
macbook-pro-de-damien:sage damien$ gulp
