從這個issue在authlogic GitHub的帳戶

Authlogic已更改其默認加密系統從SHA512到SCrypt。

看來你需要這個在你的Gemfile

gem 'authlogic', '~> 3.4.0' 
gem 'scrypt' 

如果你不想SCrypt你可以把這個

acts_as_authentic do |c| 
    c.crypto_provider = Authlogic::CryptoProviders::Sha512 
end 

在User.rb

您還可以使用SHA512可能需要指定authlogic gem的版本

gem 'authlogic', github: 'binarylogic/authlogic', ref: 'e4b2990d6282f3f7b50249b4f639631aef68b939' 

，但我想這將是儘快解決
