在 Rails 3.0 项目中运行 OSX Mountain Lion。

在 Rails 项目中尝试使用捆绑程序更新我的 gem 时，出现以下错误：

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.

ERROR:  Error installing ffi:
    ERROR: Failed to build gem native extension.

        /Users/victorstan/.rvm/rubies/ruby-1.9.2-p320/bin/ruby extconf.rb
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.

...

You have to install development tools first.

我安装了 XCode 以及命令行工具。

你应该使用：

sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2

另请参阅在 Mountain Lion和https://gist.github.com/1860511上安装 ImageMagick 和 rmagick 的问题。

如果您为 Xcode 重新安装命令行工具，它应该可以正常工作。这是执行此操作的链接： https ://developer.apple.com/downloads/index.action?=Command%20Line%20Tools%20%28OS%20X%20Mountain%20Lion%29
