Not a project issue, it's a problem with your node and npm setup. 1.- Try install npm as root: $ sudo node install npm -g 2.- Change permissions of /Users/test/.npm, seems like you have run sudo npm sometime without -g parameter. So do either: chown -R your_username /Users/test/.npm or rm -rf /Users/test/.npm
