ruby-on-rails - Rails 2.3.10错误

Question

我正在升级我的Rails 2.3.8应用程序，但出现了一个奇怪的错误。

Rails 2.3.8根本没有问题。
和堆栈跟踪不能帮助我。
任何想法？

我正在使用ruby 1.9.2，rails 2.3.10和bundler。

谢谢

我看起来this rails bug是相关的。简而言之，就是cvs和svn目录存在问题。
要安装猴子补丁，请将其添加到config / preinitializer.rb

gem 'rails'
require 'initializer'

module Rails
  class VendorGemSourceIndex

    def version_for_dir(d)
      version = d.split('-').find { |s| s.match(/^\d(\.\d|\.\w+)*$/) }
      Gem::Version.new(version) if version
    end

  end 
end
