Node npm start - cannot find module 'mongodb'

Question

I was following the Christopher Buechler tutorial (http://cwbuecheler.com/web/tutorials/2013/node-express-mongo/)for getting started with Node/Express/MongoDB. I made it to Step 6 where where I'm trying to display the userlist on the local host but I can't get npm start to work.

When I do npm start it says cannot find module 'mongodb'

As per one helpful person in the comments: I had to do npm install mongo --save and npm install monk --save

but this has not helped npm start to work.

What's next? I retraced my footsteps to make sure I haven't missed anything. Here is what my command line says:

C:\node>cd nodetest1

C:\node\nodetest1>npm start

nodetest1@0.0.1 start C:\node\nodetest1 node ./bin/www

module.js:340 throw err; ^ Error: Cannot find module 'mongodb' at Function.Module._resolveFilename (module.js:338:15) at Function.Module._load (module.js:280:25) at Module.require (module.js:364:17) at require (module.js:380:17) at Object.

Thank you for the help!
