尝试通过 RVM 将 RubyGems 升级到 1.8.10 版并出现此错误：
$ rvm rubygems latest
Removing old Rubygems files...
Installing rubygems-1.8.10 for ruby-1.9.2-p180 ...

检查日志文件 (rubygems.install.log) 时，这是从安装生成的：

RubyGems 1.8.10 installed
有人知道更新可能有什么问题吗？也尝试通过 RVM 删除 rubygems，然后再次运行更新，但没有成功。
更新： 好像 rvm 无法运行 Ruby 1.9.2。
$ rvm use 1.9.2 WARN: ruby ruby-1.9.2-p290 is not installed. To install do: 'rvm install ruby-1.9.2-p290'
所以安装1.9.2-p290之后rubygems的安装就成功完成了。
$ rvm use 1.9.2
Using /Users/foo/.rvm/gems/ruby-1.9.2-p290
$ rvm rubygems latest
Removing old Rubygems files...
Installing rubygems-1.8.10 for ruby-1.9.2-p290 ...

这对我有用。

似乎 rvm 无法运行 Ruby 1.9.2。 $ rvm use 1.9.2 WARN: ruby ruby-1.9.2-p290 没有安装。要安装： 'rvm install ruby-1.9.2-p290' 所以在安装 1.9.2-p290 之后，rubygems 的安装成功完成。
