Question

I am using the gem of devise and I am getting error LoadError in Devise::RegistrationsController#create cannot load such file -- bcrypt_ext.. I tried to do some research regarding to this problem and also tried to follow the instruction given(https://stackoverflow.com/questions/35422463/loaderror-in-deviseregistrationscontrollercreate-cannot-load-such-file-bc)

But still having this problem. Any suggestion?

Uncomment the line `# gem 'bcrypt', '~> 3.1.7'` and run `bundle install` — max, Apr 18 '17 at 00:07
I checked my gem, and it is now listed bcrypt (3.1.11 ruby x86-mingw32) bcrypt-ruby (3.1.5 x86-mingw32) and I also restart the serverf — Angel, Apr 18 '17 at 00:18
Wups, right now I cant run the rails server because it gives me this error "C:/RailsInstaller/Ruby2.3.0/lib/ruby/gems/2.3.0/gems/activesupport-5.1.0.rc1/lib/active_support/dependencies.rb:292:in `require': cannot load such file -- bcrypt_ext (LoadError) " — Angel, Apr 18 '17 at 00:29

I was also having the same error, and my problem got fixed, please try solution 3

The problem is the compiled windows gem. It would be better if it were deleted and only include the pure ruby version.

Solution one:

You can copy bcrypt_ext.so from \lib\2.1 to \lib the same folder where is bcrypt.rb

Solution two:

You can use the gem install bcrypt --platform=ruby even if I had trouble to select that from rails which it always use the compiled version

Solution three:

git clone https://github.com/codahale/bcrypt-ruby.git

cd bcrypt-ruby

gem build bcrypt.gemspec

gem install gem-compiler

gem compile bcrypt-3.1.10.gem

gem install bcrypt-3.1.10-x64-mingw32.gem --local

In my case on Windows 7 64bit I had the *bcrypt-3.1.11.gem* and *bcrypt-3.1.11-x86-mingw32.gem* which I used in your **Solution three**, that worked for me. Thanks! — Roan, Aug 19 '17 at 08:10
