rubygems 1.3.7在Ubuntu上安装期间TypeError（在’merge’中）
在更新的Ubunutu x86_64上使用rvm安装ruby-1.9.2-p0时，我在`merge’中不断出现错误：无法将String转换为Hash（TypeError）。 已经安装了rvm笔记中的所有apt软件包和rubygems手册中的软件包。 我相信当RVM尝试安装rubygems时会出现错误。
我也得到与系统ruby安装ruby gems相同的错误。 我认为这是一个依赖性问题。
我之前在i386和x86_64上都编译过Ubuntu，但从未遇到过这个问题。 我错过了什么/做错了什么？
通过系统ruby：

解决方案很简单。
1）阅读源代码。 2）意识到system_config合并成功。 3）意识到你的user_config（.gemrc文件）中有错误。 4）修复它。 5）一切正常。
.gemrc正确的语法：
gem: --no-ri --no-rdoc
