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

我用谷歌搜索了，我发现一篇文章引导我把config.encryptor =：sha1，而不是config.encryptor =：bcrypt，但问题没有解决..

Answer 1

如果您尝试重新安装bcrypt-ruby gem？

，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并不适用于我。

bcrypt-ruby＆gt;中的错误got fixed = 3.1.10 ，但Rails 3.2锁定在 bcrypt-ruby 3.0.x 。

解决方案是：

转到较新的Rails版本（＆gt; = 4）
使用较旧的Ruby版本（2.1.x）
fork my changes并自己跟上安全更新（因为目前Rails 3.2仅支持严格的安全更新）。
