NodeJS - Error: The specified procedure could not be found.bcrypt_lib.node

Question

I have upgraded from Node.js 0.12.7 to 4.2.1, getting the following error when starting my server:

$ node server.js
C:\Users\me\documents\github\angular-express-auth\node_modules\bcrypt\node_modules\bindings\bindings.js:83
        throw e
        ^

Error: The specified procedure could not be found.

In fact the node-gyp build is failing that's causing this specific issue or vice-versa, not sure how exactly both are linked.It was working perfectly fine till the Node.js version upgrade. I have the dependencies installed (Python v2.7.3,Microsoft Visual c++ 2015), have the environmental variables setup correctly too. Please help.

It's a problem with the version mismatch between node js and bcrypt module. Uninstalled bcrypt using npm in my project and reinstalled the same, now it's successfully building the node-gyp module (bcrypt installation always builds the node-gyp and creates a new binding file) and the app is running.
