<code>brew unlink xz; bundle install; brew link xz</code>

Re-linking <code>xz</code> might not be necessary ... if for example you only have that dependency because of <code>the_silver_searcher</code> (which links directly against the non-symlinked library).

Try install libxml2 first with Homebrew.

<pre><code>brew install libxml2
</code></pre>

Then if installing with bundle

<pre><code>bundle config build.nokogiri --use-system-libraries \
 --with-xml2-include=$(brew --prefix libxml2)/include/libxml2
bundle install
</code></pre>

If installing directly with gem

<pre><code>gem install nokogiri -- --use-system-libraries \
 --with-xml2-include=$(brew --prefix libxml2)/include/libxml2
</code></pre>

If you have earlier installed nokogiri using bundler with <code>bundle config build.nokogiri --use-system-libraries</code> this setting will still be there. If you then meanwhile have solved your Xcode setup (as suggested as the primary method of installation in the nokogiri installation) then you might wanna try removing that fra from bundler <code>bundle config --delete build.nokogiri</code> and try again doing <code>bundle install</code>.

I'm having troubles installing Nokogiri (1.6.8.1) on Mac OS Sierra 10.12.

I tried using <code>brew install libxml2 libxslt</code> and then referencing the install directories using command line options but it didn't help.
