The nokogiri install tutorial provides the solution:
# bash
brew unlink gcc
gem uninstall nokogiri
xcode-select --install
gem install nokogiri
If you don't have Xcode 6.1, yet, you may install it from the apple developer download site (section additional tools), as described in this blog post.

I suggest an update to Oskar's answer, replace MacOSX10.9.sdk to MacOSX10.10.sdk, tested on OS X 10.10
gem install nokogiri -- \
--with-iconv-lib=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/lib \
--with-iconv-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include
回答3:
I was successfull with:
gem install nokogiri -- \
--with-iconv-lib=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/lib \
--with-iconv-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include
回答4:
without brew and other stuff:
xcode-select --install
gem install nokogiri -- --use-system-libraries
回答5:
In my case I had upgraded Xcode and forgot to install the command line tools so install was not able to run compiler.
The following installs the command line tools:
xcode-select --install
回答6:
Just in case if some one is still not able to resolve it as I do with the above mentioned solution, then this is the alternate
gem install nokogiri -- --user-system-libraries
or using bundle
bundle config build.nokogiri --use-system-libraries
bundle install

This seems to be get nokogiri to install, not sure yet about the operational state.
brew install libiconv
gem install nokogiri -- --with-iconv-include=/usr/local/opt/libiconv/include/ --with-iconv-lib=/usr/local/opt/libiconv/lib/
Install log:

************************************************************************
IMPORTANT! Nokogiri builds and uses a packaged version of libxml2.
If this is a concern for you and you want to use the system library
instead, abort this installation process and reinstall nokogiri as
follows:
gem install nokogiri -- --use-system-libraries
If you are using Bundler, tell it to use the option:
bundle config build.nokogiri --use-system-libraries
bundle install
However, note that nokogiri does not necessarily support all versions
of libxml2.
For example, libxml2-2.9.0 and higher are currently known to be broken
and thus unsupported by nokogiri, due to compatibility problems and
XPath optimization bugs.

on 10.9 with XCode 6.1 i had to throw in --use-system-libraries because the customized libxslt was dying.
gem install nokogiri -- --with-iconv-lib=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/lib --with-iconv-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include --use-system-libraries
回答9:
I was experiencing this problem as well, turns out for me it was a result of having installed macports under Mavericks, and not having migrating the setup to Yosemite.
Following the instructions here:
http://trac.macports.org/wiki/Migration
Allowed me to install the older version of Nokogiri (1.5.x) that was a dependency of rspec-puppet
回答10:
I had the same problem, after installing command line tool,
gem install nokogiri -- --with-iconv-lib=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/lib --with-iconv-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include --use-system-libraries
Doesn't necessarily work as it keeps saying check the software update(it's already the latest version). Instead, I used sudo gem install nokogiri --pre which worked in the end
