bcrypt loading error in windows 10

Question

now I am trying to install bcrypt in windows 10, but I got an loading error whenever running webrick server as the following.

C:/Ruby22-x64/lib/ruby/gems/2.2         


        

Answer 1

In your gem file add:

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

This worked for me on Windows 10 64 Bit.

Answer 2

Try fix Gemfile

gem 'bcrypt', '~> 3.1.10', require: false
if Bundler::WINDOWS
  gem 'bcrypt-ruby', '~> 3.0.0', require: false
else
  gem 'bcrypt', '~> 3.1.10', require: false
end

Answer 3

gem uninstall bcrypt and gem install bcrypt --platform=ruby was a temporary fix, broke after bundle install.

My Fix =>

gemfile.lock:

(Delete bcrypt from gemfile.lock)

Change devise to:

devise (4.4.3)
  bcrypt (~> 3.0)

< scroll down to DEPENDENCIES >

DEPENDENCIES

  bcrypt!

  devise (~> 4.3)

Gemfile:

gem 'devise', '~> 4.3'

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

To commandline: gem uninstall bcrypt bundle install

Answer 4

It took me few hours to get this done but please feel free to share it.The root problem here is that ruby itself comes with bcrypt version 3.1.5 which is having bugs with the newer updates. However when you install or uninstall the bcrypt you are leving behind bcrypt-ruby which it always asks for first and hence all what you are doing won't go through so what to do ? 1- uninstall bcrypt and bcrypt-ruby by running these two commands: gem uninstall bcrypt and

 gem uninstall bcrypt-ruby

2- Install it again with

gem install bcrypt --platform=ruby 

In your Gemfile write

 gem 'bcrypt','~>3.1.11' 

NOW as i write these lines the latest version is 3.1.11 but whatever version is updated just add it from their gem page. Run bundle install and it should work just fine.
