Failed to load c++ bson extension with windows

I know this has been asked many times but I still get this after installing mongoose on Windows 8. I don't even see anything bson related in this path:

node_modules\mongoose\node_modules\mongodb\node_modules

2015-03-31  07:08 PM    <DIR>          .
2015-03-31  07:08 PM    <DIR>          ..
2015-03-31  07:08 PM    <DIR>          mongodb-core
2015-03-31  07:08 PM    <DIR>          readable-stream

Am I doing the installation wrong?
