node.js - Failed to load c++ bson extension with windows -

i know has been asked many times still after installing mongoose on windows 8. don't see bson related in 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
