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 

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..

anyone?

回答1:

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 

回答2:

Reinstalling bcrypt-ruby hasn't worked for me.

The bug got fixed in bcrypt-ruby >= 3.1.10, but Rails 3.2 locked on bcrypt-ruby 3.0.x.

Solution would be to either:

• move to newer Rails version (>=4)
• use older Ruby version (2.1.x)
• fork my changes and keep up with security updates by yourself (since currently Rails 3.2 supports only severe security updates)
