为什么会发生以下情况，我该如何排序？
在OS X Leopard（v10.5.6）上：
$ ./script/server
Rails requires RubyGems >= 1.3.1 (you have 1.2.0). Please `gem update --system` and try again.
$ sudo gem update --system
Updating RubyGems
Nothing to update
无法升级RubyGems 1.2
原标题：
最佳回答
我自己还没有遇到这个问题，但我认为这是一个可能的解决方案：
$ sudo gem install rubygems-update
Successfully installed rubygems-update-1.3.0
1 gem installed
$ sudo update_rubygems
这应该允许您通过特定的updater-gem安装更新。
