User.rb

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :token_authenticatable, :confirmable,
  # :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :remember_me
end

我已经google了，我找到一篇文章，让我把config.encryptor =：sha1，而不是config.encryptor = ：bcrypt，但问题没有解决..

i've googled and i found a article that lead me to put config.encryptor = :sha1, instead of config.encryptor = :bcrypt, but the problem wasn't solved..

任何人？

推荐答案

如果您尝试重新安装 bcrypt-ruby gem？

What if you tried reinstalling the bcrypt-ruby gem?

  # Remove all versions of bcrypt-ruby
  sudo gem uninstall bcrypt-ruby

  # Install the latest version 
  sudo gem install bcrypt-ruby
