ruby-on-rails - ActiveRecord::Extensions::SqliteRegexp:Class 的未定义方法 class_inheritable_accessor

Question

我最近安装了“ar-extension”gem。安装后，当我运行 rails c 或 rails s 时出现以下错误:

/usr/local/rvm/gems/ruby-1.9.2-p320/gems/ar-extensions-0.9.2/lib/ar-extensions/extensions.rb:427:in `<class:SqliteRegexp>': undefined method `class_inheritable_accessor' for ActiveRecord::Extensions::SqliteRegexp:Class (NoMethodError)

我用谷歌搜索错误但徒劳无功..请帮助我知道到底出了什么问题。

Answer 1

您尝试使用的 gem 与 rails 3.2 不兼容。 class_inheritable_accessor 已被弃用，取而代之的是 class_attribute。

你可以寻找这个 gem 的 rails 3.2 fork，做你自己的端口，或者搜索替代品。
