Gem 安装错误：NameError

Question

自从我更新到 Mac OSX Lion 后，我无法安装任何 Gem。 每次我尝试安装任何 gem 时，终端窗口都会挂起。 我已经卸载了包括 ruby​​ 在内的所有内容并重新安装了 Ruby Gems，但这并没有解决问题。

运行后： gem install rails --debug 我明白了（只显示第一行）：

Exception `NameError' at /opt/local/lib/ruby/site_ruby/1.8/rubygems/command_manager.rb:177 - uninitialized constant Gem::Commands::InstallCommand
Exception `LoadError' at /opt/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36 - no such file to load -- psych
Exception `LoadError' at /opt/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:62 - no such file to load -- psych

Exception `EOFError' at /opt/local/lib/ruby/1.8/net/http.rb:1060 - end of file reached

GEM env 给出了这个：

RubyGems Environment:
  - RUBYGEMS VERSION: 1.8.8
  - RUBY VERSION: 1.8.7 (2011-06-30 patchlevel 352) [i686-darwin11]

     - :sources => ["http://rubygems.org/", "http://gems.github.com"]
  - REMOTE SOURCES:
     - http://rubygems.org/
     - http://gems.github.com

我在这里完全一无所知，我希望有人能给我一些提示或什么。 运行 OSX Lion 的 MAC Book PRO

谢谢 马可

嘿，我有一个非常相似的问题，

我使用 RVM Click here! 升级到 Ruby 1.9.2

它有自己的方式来管理每个 Ruby 实例的 Gem，并帮助我了解 gem 的保存位置等...如果你有阅读，你应该去那里！

如果没有帮助，我很抱歉，但可能值得一试！
