ruby-on-rails-3 – 未定义的方法`write_inheritable_attribute’for Rails :: Generator :: Base：Class(NoMethodError)

我正在铁路上工作,突然间服务器停止工作.它的工作正常,我使用了以下命令[platform windows 7]

gem install -v=2.3.5 rails

当我使用rails s时,会出现以下错误：

c:/Ruby193/lib/ruby/gems/1.9.1/gems/rails-2.3.5/lib/rails_generator/options.rb:32:in `default_options': undefined method `write_inheritable_attribute' for Rails::Generator::Base:Class (NoMethodError)

解决方法

我也有同样的问题,但是这是宝石rmagick的结果.

我跑了以下：

gem uninstall rmagick 
gem cleanup

然后在堆栈中重新运行捆绑,它再次为我工作.
