I have almost tried every solution but i am unable to resolve this issue. Can any body please help me to sort out this issue. I already tried following:

Firstly uninstall bcrypt and bcrypt-ruby by running these two commands: gem uninstall bcrypt and gem uninstall bcrypt-ruby Install it again with gem install bcrypt --platform=ruby In your Gemfile write gem 'bcrypt-ruby', '3.1.5', :require => 'bcrypt' Run bundle install

Answer 1

我设法通过在Gemfile中添加以下行来解决此问题。...

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

Answer 2

After trying several methods, the above worked for me: 1) Stop all rails servers. 2) Add : gem 'bcrypt', git: ' https://github.com/codahale/bcrypt-ruby.git ', :require => 'bcrypt' to the gemfile. 3) bundle install.
