我是一个相当新的 ruby 开发人员，尤其是 rails，但我确实有一些 perl 和 php 经验。无论如何，我正在尝试rails使用最新的 ruby 包在 Ubuntu 10.10 上配置版本 3 v1.9.2-p136：. 情况不太好，虽然比p0：至少他们包括yaml.rb和朋友，所以我不会花时间把他们拼凑在一起。但是，我仍然遇到 YAML 包的问题，每当我尝试安装或配置任何gem 或包时，它都会表现出来。我已经安装了导轨synaptic；这只是为了展示问题。
gem i rails
ERROR: Loading command: install (NameError)
uninitialized constant Syck::DefaultResolver
ERROR: While executing gem ... (NameError)
uninitialized constant Gem::Commands::InstallCommand
当我尝试安装时，这实际上出现了redmine：synaptic它现在说每个突触安装都以失败告终，所有这些都是因为：
rake aborted!
