ROR的WEBrick服務器啓動錯誤

Question

當我嘗試啓動了MacPorts的安裝軌道的WEBrick服務器上的Ruby把它放下像一年後重新回到我的回報率培訓我得到了執行ruby -d script/server以下錯誤：

Exception `LoadError' at /opt/local/lib/ruby/site_ruby/1.8/rubygems.rb:1215 - no such file to load -- rubygems/defaults/operating_system

from /opt/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `require' 

所引起這些錯誤，因爲Rails項目我做之前，與舊的寶石或Ruby版本（我每次更新我的MacPorts的時間沒有更新）製成？我該如何補救？

更新

實測值Uninitialized constant ActiveSupport::Dependencies::Mutex (NameError)這是類似的。現在更新寶石並儘快重試。

更新2級

更新了所有的寶石剛剛得到一個錯誤：

Updating mysql2 
ERROR: While executing gem ... (Gem::GemNotFoundException) 
    Could not find a valid gem 'mysql2' (0.3.11) locally or in a repository 

錯誤：

    from /opt/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `require' 
    from script/server:3 

依然存在，但可能需要某種形式重啓

更新3

我將require 'thread'添加到config/boot.rb的頂部，如前面提到的線程的@thekingoftruth的答案中所建議的。現在Webrick開始了。我收到很多錯誤仍然說：

Answer 1

正如更新中所示，我自己解決了這個問題。我現在在我的OSX Lion上使用RVM。
