'Rails服務器'< - 不起作用

-2

我是Rails的新手。我被要求對現有項目進行一些改進。我從Heroku下載了它。它使用紅寶石「1.8.7」，感謝rvm我也有它的項目的目錄。我設法捆綁更新和捆綁安裝。現在我嘗試「軌道服務器」，我得到錯誤信息：'Rails服務器'< - 不起作用

/home/jacek/.rvm/gems/ruby-1.8.7-p371/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:55: uninitialized constant ActiveSupport::Dependencies::Mutex (NameError)

    from /home/jacek/.rvm/gems/ruby-1.8.7-p371/bin/ruby_noexec_wrapper:14

我怎樣才能解決這個問題？謝謝！
