Answer 1

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

Answer 2

without brew and other stuff:

xcode-select --install 
gem install nokogiri -- --use-system-libraries

Answer 3

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

Answer 4

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

Answer 5

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

Answer 6

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

Answer 7

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

Answer 8

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.

Answer 9

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

Answer 10

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:

Maxims-MacBook-Air:ScrapingTheApple maximveksler$ gem install nokogiri -- --with-iconv-include=/usr/local/opt/libiconv/include/ --with-iconv-lib=/usr/local/opt/libiconv/lib/

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.
