安装ri文档时Ruby gem失败

我想在我的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一些安装由Ruby gem完成的地步.特别是：

gem install bundler

这显示以下错误：

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

然后我尝试重建Ruby包

gem pristine --all

这没有用.以下是安装的Ruby包列表：

即使捆绑包出现在列表中,它似乎也没有正确安装.

我希望有人可以帮助我,因为我真的需要GitLabHQ才能工作.

解决方法

不是一个修复,真的,但一个解决方法：把这一行：

gem: --no-rdoc --no-ri

到一个名为〜/ .gemrc的文件中,跳过rdoc和ri文档的安装(无论如何你可能不想在你的系统上安装 – 它会加快安装过程的速度).
