libxml2 is missing. Please locate mkmf.log to investigate how it is failing.
缺少 libxml2。请找到 mkmf.log 以调查它是如何失败的。
*** 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.

i fiddled around with this for quite a while and the following worked for me..
我摆弄了很长一段时间，以下对我有用..
1) install libxml2 with homebrew
1）用自制软件安装libxml2
brew install libxml2
2) install the gem via
2）通过安装gem
sudo env ARCHFLAGS="-arch x86_64" gem install nokogiri:1.6.4.1 -- --use-system-libraries --with-xml=/usr/local/Cellar/libxml2/

For any who are still getting "libxml2 version 2.6.21 or later is required!" message, removing --use-system-libraries from hlv's step 2 above, worked for me.
对于仍然“需要 libxml2 版本 2.6.21 或更高版本！”的任何人。消息，从上面的 hlv 步骤 2 中删除 --use-system-libraries，对我有用。
sudo env ARCHFLAGS="-arch x86_64" gem install nokogiri:1.6.4.1 -- --with-xml=/usr/local/Cellar/libxml2/2.9.2/

I finally ended up with this version independent line:
我终于得到了这个版本独立的行：
sudo env ARCHFLAGS="-arch x86_64" gem install nokogiri -n /usr/local/bin -- --with-xml=/usr/local/Cellar/libxml2/

This worked for me (assuming Xcode is installed):
这对我有用（假设安装了 Xcode）：
gem install nokogiri -- --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.?platform/Developer/SDKs/MacOSX10.9.sdk/usr/include/libxml2 --use-system-libraries

(For MacOX 10.12.x) Perhaps you want to brew install libxml2and also try linking into /usr/local/first: brew link --force libxml2, then try that gem install nokogiri -- --use-system-libraries.
（对于 MacOX 10.12.x）也许您想brew install libxml2并尝试先链接到/usr/local/: brew link --force libxml2，然后再尝试gem install nokogiri -- --use-system-libraries.

Using ports:
使用端口：
gem install nokogiri -- --use-system-libraries --with-xml=/opt/local/lib/libxml2.a
回答by alijandro
My solution, using ports:
我的解决方案，使用端口：
sudo ARCHFLAGS='-arch x86_64' gem install nokogiri -- --use-system-libraries
sudo ARCHFLAGS='-arch x86_64' gem install nokogiri -- --use-system-libraries
By default, it will compile for x86_64 and i386, architecture for i386 should disabled, because the dependencies libraries in port only provide x86_64 version by default.
默认情况下，它会为 x86_64 和 i386 编译，应该禁用 i386 的架构，因为端口中的依赖库默认只提供 x86_64 版本。

This is a bit of a rehash of all the other answers, but this worked for me:
这是对所有其他答案的重新整理，但这对我有用：
gem install nokogiri -v '1.6.6.2' -- --with-iconv-dir=/usr/local/Cellar/libiconv/1.16 --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/libxml2 --use-system-libraries
