我正在跑步：

ruby -v
ruby 1.8.7 (2012-02-08 patchlevel 358) [universal-darwin12.0]

rails -v
Rails 3.2.13

我不知道我还丢失了什么宝石和/或碎片

任何帮助都会很好

另外，很抱歉写了这么长的文章

您是否安装了XCode的命令行工具？如果可能的话，我还建议在系统上使用ruby。是的，我确实安装了xCode的cl工具。你是说RVN vs Gem吗？我是说RVM安装一个不同于系统ruby的ruby，并用它来管理你的Gem。这是一个隔离不同版本ruby和已安装gems的好工具。我认为前面的答案会有所帮助。安装json_pure没有帮助
