LoadError：无法加载此类文件--bcrypt_ext

Question

I have tried to deploy devise authentication on my rails app.

I am getting this issue

"cannot load such file -- bcrypt_ext"

I see it is a common issue amongst windows based computers but the answers to other questions have not helped me yet.

I am running Windows 8 x64 with x86 ruby and devkit

Answer 1

try

C:\> gem install --no-ri --no-rdoc bcrypt
C:\> cd (path to gems root)\bcrypt-3.1.7-x86-mingw32\ext\mri
C:\(path to gems root)\bcrypt-3.1.7-x86-mingw32\ext\mri> ruby extconf.rb
C:\(path to gems root)\bcrypt-3.1.7-x86-mingw32\ext\mri> make
C:\(path to gems root)\bcrypt-3.1.7-x86-mingw32\ext\mri> make install

Answer 2

bcrypt_ext.so file is missing -if you manually copy it to proper folder - in my case \\Ruby23\\lib\\ruby\\gems\\2.3.0\\gems\\bcrypt-3.1.11-x86-mingw32\\lib - it helps. :)

Answer 3

This worked for me: https://github.com/codahale/bcrypt-ruby/issues/142

-Uninstall all bcrypt versions: gem uninstall bcrypt

select option 3 (uninstall all)

-Uninstall all bcrypt-ruby versions: gem uninstall bcrypt-ruby

select option 3 (uninstall all)

replace the line in your gemfile by:

to add this line to the gemfile: gem 'bcrypt', platforms: :ruby

did not work for me though but to point the gemfile to the git repository did:

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

bundle install

and you should be good to go

At this link https://github.com/codahale/bcrypt-ruby/issues/142

Somebody mentioned this solution

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

And it worked for me
