I am trying to install Rails 4.2.0 on my computer, but I am having problems installing Nokogiri. I followed these steps in the first answer: " install the package in Nokogiri ", but when I run brew install nokogiri , I get the following:
Activating libxslt 1.1.28 (from /Users/dseibert/.rvm/rubies/ruby-2.2.0/lib/ruby/gems/2.2.0/gems/nokogiri-1.6.6.2/ports/x86_64-apple-darwin14.0.0/libxslt/1.1.28)... checking for main() in -llzma... yes checking for xmlParseDoc() in libxml/parser.h... no checking for xmlParseDoc() in -lxml2... no checking for xmlParseDoc() in -llibxml2... no ----- libxml2 is missing.

I cannot find the mkmf file to search for the details of my libxml2 file, and I cannot see either the libxml2 file or the Nokogiri folder in my Ruby source folder.
And when I run brew install libxml2 , I get Warning: libxml2-2.9.2 already installed .
Following the comment, I got the answer: Successfully installed nokogiri-1.6.6.2 . But when I ran sudo gem install rails , I returned the above error again.
