BCrypt :: Errors :: InvalidSalt：无效的盐设计
当我尝试创建新用户时，我收到此错误，就像这样
>> User.create(:email=>"nandosousafr@gmail.com", :password => "hello") BCrypt::Errors::InvalidSalt: invalid salt from /Library/Ruby/Gems/1.8/gems/bcrypt-ruby-3.0.1/lib/bcrypt.rb:56:in `hash_secret' from /Library/Ruby/Gems/1.8/gems/bcrypt-ruby-3.0.1/lib/bcrypt.rb:161:in `create' from /Library/Ruby/Gems/1.8/gems/devise-2.1.2/lib/devise/models/database_authenticatable.rb:110:in `password_digest' from /Library/Ruby/Gems/1.8/gems/devise-2.1.2/lib/devise/models/database_authenticatable.rb:37:in `password=' from /Library/Ruby/Gems/1.8/gems/activerecord-3.2.2/lib/active_record/attribute_assignment.rb:85:in `send' from /Library/Ruby/Gems/1.8/gems/activerecord-3.2.2/lib/active_record/attribute_assignment.rb:85:in `assign_attributes' from /Library/Ruby/Gems/1.8/gems/activerecord-3.2.2/lib/active_record/attribute_assignment.rb:78:in `each' from /Library/Ruby/Gems/1.8/gems/activerecord-3.2.2/lib/active_record/attribute_assignment.rb:78:in `assign_attributes' from /Library/Ruby/Gems/1.8/gems/activerecord-3.2.2/lib/active_record/base.rb:495:in `initialize' from /Library/Ruby/Gems/1.8/gems/activerecord-3.2.2/lib/active_record/persistence.rb:44:in `new' from /Library/Ruby/Gems/1.8/gems/activerecord-3.2.2/lib/active_record/persistence.rb:44:in `create' from (irb):3 >

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，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..
任何人？
如果您尝试重新安装bcrypt-ruby gem怎么办？
# Remove all versions of bcrypt-ruby sudo gem uninstall bcrypt-ruby # Install the latest version sudo gem install bcrypt-ruby
重新安装bcrypt-ruby对我没用。
该错误已在bcrypt-ruby> = 3.1.10中 得到修复 ，但Rails 3.2已锁定在bcrypt-ruby 3.0.x上 。
解决方案是：
- 转移到更新的Rails版本（> = 4）
- 使用较旧的Ruby版本（2.1.x）
- 分叉我的更改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）
