未初始化的常量Syck :: DefaultResolver

Question

我是紅寶石，尤其是Rails的新手，但是我確實有一些Perl和PHP的經驗。 無論如何，我試圖使用最新的ruby軟件包v1.9.2-p136在Ubuntu 10.10上配置rails版本3。 雖然效果不如p0好，但效果不是很好：至少他們包括了yaml.rb和朋友，因此我沒有花時間讓他們在一起。 但是，我仍然對YAML軟件包有問題，每當我嘗試安裝或配置任何 gem或軟件包時，它都會顯現出來。 我已經通過synaptic安裝了滑軌； 這只是為了展示問題。

gem i rails
ERROR:  Loading command: install (NameError)
uninitialized constant Syck::DefaultResolver
ERROR:  While executing gem ... (NameError)
uninitialized constant Gem::Commands::InstallCommand

當我嘗試通過synaptic安裝redmine時，實際上顯示了這一點：現在它說每次突觸安裝均以失敗告終，原因如下：

我編寫了有關安裝此版本Ruby的指南： http : //ryanbigg.com/2010/12/ubuntu-ruby-rvm-rails-and-you 。 它應該立即使您啟動並運行。
