Building Nokogiri with a packaged version of libxml2-2.9.4
with the following patches applied:
    - 0001-Fix-comparison-with-root-node-in-xmlXPathCmpNodes.patch
    - 0002-Fix-XPointer-paths-beginning-with-range-to.patch
    - 0003-Disallow-namespace-nodes-in-XPointer-ranges.patch

Team Nokogiri will keep on doing their best to provide security
updates in a timely manner, but if this is a concern for you and want
to use the system library instead; abort this installation process and
reinstall nokogiri as follows:

    gem install nokogiri -- --use-system-libraries
        [--with-xml2-config=/path/to/xml2-config]
        [--with-xslt-config=/path/to/xslt-config]

If you are using Bundler, tell it to use the option:

    bundle config build.nokogiri --use-system-libraries
    bundle install

Note, however, that nokogiri is not fully compatible with arbitrary
versions of libxml2 provided by OS/package vendors.

Answer 1

Sometimes this is a pain, I'm not even sure why this happens randomly. however, here is how I solve it most of the time.

brew unlink xz
gem install nokogiri
brew link xz

If that does not help, throws an error again with libxml2, you should do the following

brew install libxml2

and then

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