我将我的 Mac OSX 版本更改为 Lion。但是我无法创建 Rails3 应用程序。
我使用 rvm 1.9.2 并选择 ruby 1.9.2-p290 来创建 Rails 3 应用程序。
一切似乎都很好。当我开始创建一个新应用程序时
rails new new_my_app
我看到这个错误,
Installing json (1.6.6) with native extensions

An error occured while installing json (1.6.6), and Bundler cannot continue.
Make sure that `gem install json -v '1.6.6'` succeeds before bundling.
当我尝试
gem install json -v '1.6.6'
我面临这个错误
Building native extensions. This could take a while...

我应该怎么做才能解决这个问题?
谢谢。
