Error while installing hubot on ubuntu

Question

When I run yo hubot the following error comes up

npm ERR! argv "/usr/local/bin/node" "/usr/local/bin/npm" "install" "hubot"
"hubot-scripts" "hubot-diagnostics" "hubot-help" "hubot-heroku-keepalive" "hubot-google-images"
"hubot-google-translate" "hubot-pugme" "hubot-maps" "hubot-redis-brain"
 "hubot-rules" "hubot-shipit" "--save"

Why is this happening? I have tried running sudo npm install hubot-rules but it doesn't seem to work. Please help!

Turns out that you need to own the ~/.npm directory. You can run this command to do so:

$ sudo chown -R $(whoami) "$HOME/.npm"
