RVM跟蹤新項目錯誤

Question

我剛剛安裝了RVM，還安裝了ruby 1.8.7和rails 2.3.5（我以前使用的是ruby 1.9.1和rails 3），但是現在當我嘗試創建一個新項目時，

rails new project_name

我收到以下錯誤

uninitialized constant ActiveSupport::Dependencies::Mutex (NameError)
    from /Users/anandhegde/.rvm/rubies/ruby-1.8.7-p357/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require'

    from /Users/anandhegde/.rvm/gems/ruby-1.8.7-p357/bin/rails:19

我注意到在堆棧溢出中提供了一些與此相關的解決方案....與編輯boot.rb有關，但是我找不到此文件。 我是Rails的新手。任何幫助將不勝感激。

我以前見過這個錯誤，這更多與rubygems版本太高有關。 您可以使用gem update --system 1.3.6降級您的版本（似乎可以正常使用gem update --system 1.3.6
