我遇到了JSON gem和Ruby 1.9.2的问题。我正在升级到Rails 3.0.3，每当我尝试启动环境时，它都会爆炸。这是一个空的测试项目，只有JSON gem 1.4.6作为依赖项。
/Users/lee/.rvm/gems/ruby-1.9.2-p0/gems/json-1.4.6/lib/json/common.rb:66: [BUG] unknown type 0x22 (0xc given)

升级到Snow Leopard之后我遇到了一些奇怪的问题，因为它有64位差异，所以如果你升级到Snow Leopard，你可能会遇到同样的问题。
我安装了最新的XCode，然后使用rvm uninstall 1.9.2吹走了我的1.9.2安装，并使用gem update --system; gem pristine --all重建了所有宝石。
