Node cannot find module when deploying to Heroku

Thanks for the great module!
I am importing your module in my program using var mturkApi = require('mturk-api') and it all works find on my local machine. When I deploy my app to heroku, npm throws an error 'Error: cannot find module 'mturk-api'
Any idea what is going on here?
Thanks!

So i have a work around. For some reason your module does not get commited to git correctly and hence does not get deployed to heroku correctly. Is there something strange with your npmignore? Here is what I used for reference:
