Getting No such file or directory: 'jade'

[pravin-d]

I'm on OSX and have installed jade using
sudo npm install jade --global

However I still the get the error
[Errno 2] No such file or directory: 'jade'
[cmd: ['jade', '/Users/pravin-d/express-sample/views/layout.jade', '--pretty']]
[dir: /Users/pravin-d/express-sample/views]
[path: /usr/local/bin]
[Finished]

Let me know what I'm doing wrong?
