在我尝试从 4.1.8 升级到 rails 4.2.0.rc1 时，运行服务器时出现以下错误：

在我的 application.rb 文件中，我有以下内容：

require File.expand_path('../boot', __FILE__)

require 'rails/all'

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(:default, Rails.env)

module Rentlit
  class Application < Rails::Application

    config.generators.helper = false
    config.generators.assets = false
    config.generators.view_specs = false
  end
end

有关如何排除故障的任何建议？

他们已经解决了：https ://github.com/josevalim/inherited_resources/commit/6d034d913bfd9b53ea2e5b31c4056578a1b170a4 。我正在使用带有 rails 4.2.1 的最新 gem 版本，它工作正常。

对于遇到问题的任何人，请尝试bundle update inherited_resources.

老答案：

您必须使用 rails 4.2 的特定分支：

gem 'inherited_resources', github: 'josevalim/inherited_resources', branch: 'rails-4-2'

我在这里不完全确定，但我知道它action_controller/metal/responder.rb在 4.2 中已从 rails 中删除，并且几乎直接复制到respondersgem 的action_controller/responder.rb. 您可以尝试添加gem 'responders', '~> 2.0'到您的 Gemfile 以查看是否可以修复它。

FWIW：
