Answer 1

After trying for some time to install it without success (since I'm new to mongo and node), I was missing the npm link step indeed. So just to summarize, I did this:

1. npm install mongodb -g
2. cd /path/to/my/app/folder
3. npm link mongodb

With that in place, I could do this in my application file: require('mongodb').
