我在一周内没有触及我的代码，但是当我捆绑，然后尝试运行我的网络服务器时，我现在得到以下错误，这让我死在水中。包括错误输出中建议的设计加密gem不能解决问题，仍然会导致相同的错误。非常感谢任何帮助。

我遇到了同样的问题。
正如在devise的wiki上所写，你必须在你的Gemfile中添加这一行：
gem'depaise-encryptable'
来自维基：
如果您在模型上使用encryptable，则现在必须在gemfile中包含devise-encryptable。
https://github.com/plataformatec/devise/wiki/How-To:-Upgrade-to-Devise-2.1
关于警告：
从devise.rb中删除以下内容：
# Automatically apply schema changes in tableless databases
config.apply_schema = false
# If true, uses the password salt as remember token. This should be turned
# to false if you are not using database authenticatable.
config.use_salt_as_remember_token = true
