我刚刚将我的Macbook更新为Mountain Lion,但现在我无法安装一些宝石,因为下面有关于标题的错误.我环顾四周,似乎与Ruby标头缺失有关.有人建议安装Xcode,所以我从应用程序商店和Xcode命令行工具安装了完整的Xcode.但仍然没有运气.有什么建议？
ERROR: Failed to build gem native extension. (Gem::Installer::ExtensionBuildError)
checking for ffi.h... *** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.
在Macbook Pro上使用OSX 10.8.4,带有自制程序,xcode(带命令行工具)和libffi.
我已经安装了rvm和ruby-1.9.3-p448并且有一个名为omega.ecoop的gemset.有一个gemfile,列出了这个项目所需的宝石.但是,在运行捆绑检查后,我无法安装它们:
Bundler can't satisfy your Gemfile's dependencies.
这是正确的,因为它们没有安装.所以我使用:
bundle install
产生以下内容:

Installing ffi …在Rails 3.0项目中运行OSX Mountain Lion.
当尝试在Rails项目中使用bundler更新我的gem时,我得到以下错误:
An error occured while installing ffi (1.1.2), and Bundler cannot continue.
Make sure that `gem install ffi -v '1.1.2'` succeeds before bundling.
