rails-upgrade - 將rails2應用升級到rails3

我在rails2中有一個現有項目，我需要將它升級到rails3。rails-upgrade - 將rails2應用升級到rails3

我聽說了一些關於rails升級但尚未使用的東西。

當我試圖用rails-upgrade check它產生錯誤，如：

$ rails-upgrade check 
/usr/lib/ruby/gems/1.8/gems/rails-upgrade-0.0.2/lib/rails-upgrade/upgraders/routes.rb:28: undefined method `cattr_accessor' for RailsUpgrade::Upgraders::RouteRedrawer:Class (NoMethodError) 
    from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:29:in `gem_original_require' 
    from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:29:in `require' 
    from /usr/lib/ruby/gems/1.8/gems/rails-upgrade-0.0.2/lib/rails-upgrade.rb:12 
    from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:29:in `gem_original_require' 
    from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:29:in `require' 
    from /usr/lib/ruby/gems/1.8/gems/rails-upgrade-0.0.2/bin/rails-upgrade:7 
    from /usr/bin/rails-upgrade:19:in `load' 
    from /usr/bin/rails-upgrade:19

中的任何一個，請告訴我，我該怎麼我的應用程序升級到Rails3中。

'cattr_accessor'在'ActiveSupport' v 3+中定義您是否安裝了rails v 3+或者這個gem？ – Bohdan

@Bohdan Pohorilets： '$ gem list | grep activesupport' 'activesupport（3.0.9,3.0.7,3.0.5,3.0.4,3.0.3,2.3.8,2.2.2）' 仍然是同樣的問題 – Sayuj

嘗試刪除舊的寶石，也有一個類似的線程http://www.ruby-forum.com/topic/59288，並有建議運行'export RUBYOPT = -rubygems' – Bohdan

我做軌道升級與創建一個新的軌道項目到舊的。

在創建過程中，您應該檢查應該覆蓋的文件之間的差異。

對我來說，這是更新我的rails項目的最快方法。
