MongoDB error cannot find module '. /build/release/bson '

intends to write a blog system with Nodejs, found that Nodejs still exist a lot of pits. The following error question was encountered when using MongoDB:

{ [Error: Cannot find module '../build/Release/bson'] code: 'MODULE_NOT_FOUND' } 
  js-bson: Failed to load c++ bson extension, using pure JS version

Toss it over, and finally it's settled like this:

Find NPM's module MONGODB. Node_modules\mongodb\node_modules\bson\ext\index.js

and change the Bson in the catch block to the JS version of the path:

bson  =   require   ( ". /build/release/bson '   

becomes

bson  =   require   ( ". /browser_build/bson '   

If you find that the folder is not Browser_biuild (in my case), copy the file directly:

.. Node_modules\bson\build\release\bson

From

.. Node_modules\bson\browser_build\bson

MongoDB error cannot find module '. /build/release/bson '
