Since you are installing it globally, the packages would go to /usr/lib or
/use/local/lib. These folders needs sudo permission.

Try using "sudo npm install...."

Else you can install locally without g and it would be available in local
node_modules folder which would not need sudo permission.

Hope this helps...

Ritesh

Hi,
As it showing permission rights, try using

*sudo node app.js*
