Ruby 2.2.2 on Windows - LoadError: cannot load such file -- bcrypt_ext#128

May be it is related to #126 as well.
When I try to require bcrypt:

irb(main):001:0> require 'bcrypt'
LoadError: cannot load such file -- bcrypt_ext
        from C:/Ruby22-x64/lib/ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require'
        from C:/Ruby22-x64/lib/ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require'
        from C:/Ruby22-x64/lib/ruby/gems/2.2.0/gems/bcrypt-3.1.10-x64-mingw32/lib/bcrypt.rb:16:in `rescue in <top (required)>'
        from C:/Ruby22-x64/lib/ruby/gems/2.2.0/gems/bcrypt-3.1.10-x64-mingw32/lib/bcrypt.rb:12:in `<top (required)>'
        from C:/Ruby22-x64/lib/ruby/2.2.0/rubygems/core_ext/kernel_require.rb:128:in `require'
        from C:/Ruby22-x64/lib/ruby/2.2.0/rubygems/core_ext/kernel_require.rb:128:in `rescue in require'
        from C:/Ruby22-x64/lib/ruby/2.2.0/rubygems/core_ext/kernel_require.rb:39:in `require'
        from (irb):1
        from C:/Ruby22-x64/bin/irb:11:in `<main>'

it fails.
Reproduced at:

  • Windows 7 x64
  • Ruby ruby 2.2.2p95 (2015-04-13 revision 50295) [x64-mingw32]
  • bcrypt (3.1.10 x64-mingw32)

Thank you.

    Even the downgrading to bcrypt (3.1.9 x64-mingw32) does not solve the issue :(. I suppose, the only solution would be to dowwgrade Ruby to 2.1.5? FYI, there is already Ruby 2.2.3 Windows installer available.

    Hello people,
    I have with same error.
    I installed devise, but happened the error when I try to do login.
    bcrypt_ext load error

    I did tried with bcrypt-ruby require bcrypt -> not work.
    I did tried with bcrypt 3.1..7 and 3.1.9 and 3.1.10 -> not work.
    I tried with many other ways, but not solved.

    I used ruby 2.2.3 and rails 4.1.5, there are a way to workaround this?, I need the devise work with theses versions.

    Thank you so advance,

    Hello, here is my solution:

    1. Firstly 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
    3. In your Gemfile write gem 'bcrypt-ruby', '3.1.5', :require => 'bcrypt'
    4. Run bundle install

    I have Windows 10 64 bit running Ruby 2.2.2

    I should have updated my comment before after I replied to the aforementioned post on stackoverflow. I'm not sure why (and don't have time right now to figure it out), but to fix it, I did:

    I used this answer, but then make install put the resulting .so file in C:\Ruby22\lib\ruby\site_ruby\2.2.0\i386-msvcrt. The gem was not looking there for it, according the error message. So, I copied that manually to C:\Ruby22\lib\ruby\gems\2.2.0\gems\bcrypt-ruby-3.1.1.rc1-x86-mingw32\lib and it worked fine.

    +1, please fix the distributed version to build automatically.

    Temporary solution for me was to uninstall all local bcrypt versions and reinstall using the MRI version with gem install bcrypt --platform=ruby, similar to arnaskro's comment.

    @tjschuck I'm having this same issue with just having bcrypt (3.1.11 x64-mingw32) installed with Ruby 2.3.1

    Just a little update I have to uninstall all bcrypt and then manually install it from the command line with gem install bcrypt --platform=ruby. If I try and use the bundle install with gem 'bcrypt', platforms: :ruby it installs bcrypt with versions in the lib but it doesn't include 2.3.

    The issue I have should be with datamapper.
    The dm-types depends upon bcrypt-ruby (~> 3.0)
    but because I have a preinstalled bcrypt-ruby (3.1.5-x64-mingw32)
    that relies on bcrypt (>= 3.1.3)
    and I get a message after 'bundle install'
    Post-install message from bcrypt-ruby:

    #######################################################

    The bcrypt-ruby gem has changed its name to just bcrypt. Instead of
    installing bcrypt-ruby, you should install bcrypt. Please update your
    dependencies accordingly.

    #######################################################

    Why should I go in and try to correct datamapper?
    Tell them or suggest it. This is a rack app and it is getting like rails used to be.
    Sorry! Didn't mean to rant. But I'm confused.

    Confirmed this problem has reappeared for me with bcrypt (3.1.11 x64-mingw32), ruby 2.3.3, and Windows 10. Previous fix of gem uninstall bcrypt, gem install bcrypt --platform=ruby still works.

    I can confirm that gem uninstall bcrypt followed by gem install bcrypt --platform=ruby worked for me today on Windows 10 64 bit.

    If anyone is still having issues with this (especially with devise) on Windows 64 bit, try installing Ruby 64 bit, then rails as a gem (rather than using the rails installer) and then add:
    gem 'bcrypt-ruby', '~> 3.0.0', :require => "bcrypt"

    You may need to change your tzinfo-data gem to:
    gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw]

    thanks!
