在尝试从4.1.8升级到rails 4.2.0.rc1时,运行服务器时会出现以下错误:

他们已经解决了:resources/commit/6d034d913bfd9b53ea2e5b31c4056578a1b170a4。我使用的是rails 4.2.1的最新创业板发行版,它运行良好。
对于遇到这个问题的人,请尝试使用bundle update inherited_resources。
旧答案:
您必须对rails 4.2使用特定的分支:
gem 'inherited_resources', github: 'josevalim/inherited_resources', branch: 'rails-4-2'发布于 2014-12-10 23:22:49
我在这里不完全确定,但我确实知道action_controller/metal/responder.rb是在4.2中从rails中删除的,并且几乎直接复制到responders gem的action_controller/responder.rb中。您可以尝试将gem 'responders', '~> 2.0'添加到Gemfile中,以查看是否修复了它。
FWIW:
metal/ dir 4.2.2.rc2:controller/metal/ (注意没有更多的responders.rb了)。发布于 2015-06-18 13:27:17
就现在来说,快跑
