Rails 4.1.0和authlogic问题

Question

我正在使用rvm ruby 2.1.0运行最新的OSX。在bundle update到Rails 4.1.0和authlogic 3.4.1之后，当我启动服务器时，会得到以下错误：

authlogic/crypto_providers/bcrypt.rb:1:in `require': cannot load such file -- bcrypt (LoadError)

来自authlogic帐户上的这个问题

Authlogic已将其默认加密系统从SHA512更改为SCrypt。

看来你在你的档案里需要这个

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

如果你不想要SCrypt，你可以使用Sha512

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

在你的User.rb里

您还可能需要指定authlogic的版本。

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

但我想这个很快就会修好
