I solve the above issue by typing following commands:

gem uninstall bcrypt-ruby

after that we need to reinstall

gem install bcrypt --platform=ruby

now we need to add below code in the gem file

gem 'bcrypt', platforms: :ruby

by performing above steps bcrypt issue is resolved.

Try running:

In your gemfile, add

gem 'bcrypt', git: 'https://github.com/codahale/bcrypt-ruby.git', :require => 'bcrypt'

This works on Windows 10 64bit.

run cmd with adminstrator priveleges and paste this.

npm install --global --production windows-build-tools

after you install windows build tools, you can use bcrypt without any problem.
