我不能在Mac OS Lion上安装Ruby Gem'curb'

我试图捆绑安装一个应用程序，并且它一直停留在路边宝石上。这里是的Gemfile：我不能在Mac OS Lion上安装Ruby Gem'curb'

source :rubygems 

gem 'sinatra', '~>1.0' 
gem 'yajl-ruby', '~>0.7.8' 
gem 'mustache', '~>0.11.2' 
gem 'curb',  '~>0.7.8' 
gem 'coderay', '~>0.8.357' 

gem 'sinatra_auth_github' 

group :test do 
    gem 'shotgun' 
end

这里是错误：

有什么想法？

由于XCode4没有使用gcc-4.2，因此很多库都无法安装。

您必须从开发人员中心安装XCode3，它会为您创建gcc-4.2。

如何做到这一点：

注册为开发者（免费）
下载，并确保你真的安装XCode3
检查GCC-4.2文件

好运

您需要安装xcode以获取OS X开发库。

我已经安装了xcode。至少我认为我有。我可以打开xcode应用程序，甚至开始使用它。这不是说它的安装？奇怪的问题，我知道，但在寻找答案时，我在几篇文章中看到，说你必须安装它，但上述事实和它在应用商店中的安装时会显示出来，这表明它确实已安装。 – 2012-02-21 22:28:21

可能与安装时需要确认“unix开发支持”是否被检查有关？ http://stackoverflow.com/questions/2685887/where-is-gcc-on-osx-i-have-installed-xcode-already – David 2012-02-21 22:44:51

感谢您的回应。你连接的问题有一个人从CD安装的情况。我直接从App Store安装...没有选择选项或复选框来选中或取消选中。它只是安装，就是这样。 – 2012-02-21 22:49:54
