Rails 2.3.10錯誤

我正在升級我的工作軌2.3.8應用程序，但我得到了一個奇怪的錯誤。Rails 2.3.10錯誤

使用rails 2.3.8完全沒有問題。和堆棧跟蹤不能幫助我。有什麼想法？

我使用的是Ruby 1.9.2，rails 2.3.10和bundler。

它可能有助於知道什麼是對的config/environment.rb文件的第12行，並命令你試圖運行。可能是腳本/控制檯或類似的。

12行是Rails :: Initializer.run do | config |並且該命令是腳本/控制檯 – 2010-11-08 21:29:29

查看rails-2.3.10/lib/rails/vendor_gem_source_index.rb：76我會懷疑在供應商目錄中有某種「邊緣」導軌或gem。尋找供應商/鐵軌或供應商/寶石/ * – noodl 2010-11-09 10:11:51

我看起來像this rails bug是相關的。它的缺點是，cvs和svn目錄存在問題。
猴子補丁，將它添加到配置/ 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

現在移到這裏https://github.com/rails/rails/issues/972 – Anna 2011-10-10 15:39:24

也有類似的問題，它竟然是在vendor/gems目錄下的文件夾_svn。

如果是這種情況，現在只需將其重命名爲.svn即可。如果您需要從SVN進行更新，您需要將其重命名爲_svn。
