Git 发生针对jekyll的mac bundle安装错误

当我在mac上执行捆绑安装时，会发生这种情况

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

/usr/local/Cellar/ruby/2.1.2_2/bin/ruby -r ./siteconf20140725-85993-z0wc6r.rb extconf.rb 
Building nokogiri using packaged libraries.

libiconv is missing.  please visit http://nokogiri.org/tutorials/installing_nokogiri.html for help with installing dependencies.

*** 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.

提供的配置选项：

--with-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include
--with-opt-lib
--without-opt-lib=${opt-dir}/lib
--with-make-prog
--without-make-prog
--srcdir=.
--curdir

--help
--clean
--use-system-libraries

--with-zlib-include
--without-zlib-include=${zlib-dir}/include
--with-zlib-lib
--without-zlib-lib=${zlib-dir}/lib
--enable-cross-build
--disable-cross-build

extconf失败，退出代码1

Gem文件将继续安装在/Users/Dong/.rvm/gems/ruby-2.1.2/gems/nokogiri-1.6.3.1中以供检查。 结果记录到/Users/Dong/.rvm/gems/ruby-2.1.2/extensions/x86_64-darwin-13/2.1.0/nokogiri-1.6.3.1/gem_make.out 安装nokogiri（1.6.3.1）时出错，Bundler无法启动 继续。 在绑定之前，请确保

gem安装nokogiri-v'1.6.3.1'

成功。

然后我也错误地转到了这一页。我能为这个做些什么

只需重新安装

libiconv

。它在我的机器上工作。

我以前做过，但不工作。谢谢！无论如何
