尝试在 Ruby on Rails 7.0.0 中安装设备时出错

Question

我正在尝试在 Rails 版本中安装 devise，但出现最新版本 devise 的错误

我尝试过其他设备版本，但它已更新到最新，

这是错误：

错误来源

您使用的 Devise 版本调用名为 的方法reference。 https://github.com/heartcombo/devise/blob/c82e4cf47b02002b2fd7ca31d441cf1043fc634c/lib/devise.rb#L320-L323

def self.ref(arg)
  ActiveSupport::Dependencies.reference(arg)
  Getter.new(arg)
end

Rails 6中存在该方法： https ://github.com/rails/rails/blob/6-0-stable/activesupport/lib/active_support/dependency.rb#L651-L653

它已在 Rails 7 中删除： https ://github.com/rails/rails/blob/main/activesupport/lib/active_support/dependency.rb

Rails 7.0.0.alpha1 变更日志中的这一行对此进行了解释。

ActiveSupport::Dependency 的私有内部类已被删除，例如 ActiveSupport::Dependencies::Reference、ActiveSupport::Dependency::Blamable 等。

https://github.com/rails/rails/blob/main/activesupport/CHANGELOG.md#rails-700alpha1-september-15-2021

修复：升级设备

Devise 已经发布了兼容 Rails 7 的4.8.1bundle update devise版本。运行即可升级。
