class User < ActiveRecord::Base 
    # Include default devise modules. Others available are:

    # :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GOOGLE了，我发现，导致我把config.encryptor一篇=：SHA1，而不是config.encryptor =：bcrypt，但没有解决问题..

的人？

Answer 1

如果您尝试重新安装bcrypt-ruby宝石，该怎么办？

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

    # Install the latest version 
    sudo gem install bcrypt-ruby 

Answer 2

重新安装bcrypt-ruby没有为我工作。

在bcrypt旁注> = 3.1.10虫子got fixed，但Rails的3.2锁定bcrypt-红宝石3.0.x的。

的解决办法是要么：

• 移动到新的Rails版本（> = 4）
• 使用旧版本的Ruby（的2.1.x）
• 叉my changes并跟上安全更新（因为目前Rails 3.2只支持严重的安全更新）
