我正在尝试在我的 Debian 6.0.4 机器上安装 GitLabHQ。这是 2012 年 4 月 13 日的全新安装。现在我已经到了需要通过 Ruby gem 完成一些安装的地步。尤其是：
gem install bundler
这揭示了以下错误：
Successfully installed bundler-1.1.3
1 gem installed
Installing ri documentation for bundler-1.1.3...
ERROR: While executing gem ... (ArgumentError)
undefined class/module Encoding
然后我尝试用
gem pristine --all
这没有帮助。以下是已安装的 Ruby 软件包列表：

我希望有人可以帮助我，因为我真的需要 GitLabHQ 才能工作。
