Question

我正在升级我的工作轨道2.3.8应用程序，但我遇到了一个奇怪的错误。

使用rails 2.3.8完全没有问题。并且堆栈跟踪无法帮助我。有什么想法吗？

我正在使用ruby 1.9.2，rails 2.3.10和bundler。

Answer 1

我看起来this rails bug是相关的。缺点是cvs和svn目录存在问题猴子补丁，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

Answer 2

了解config / environment.rb的第12行以及您尝试运行的命令可能会有所帮助。大概是脚本/控制台或类似的。

Answer 3

有一个类似的问题，结果是_svn / vendor目录中的gems文件夹。

如果是这种情况，现在只需将其重命名为.svn。如果您需要从SVN更新，则需要将其重命名为_svn。
