This means if you do not have Libxml2 installed on the Linux or OS X you will face exactly the same problem. In order to install C/C++ Ruby extensions on each operating system you must have build tools and all dependencies installed. However this problem is not inherent solely to Windows and Ruby. This will happen whenever you try to install native gems that do not have pre-built binaries for Windows system and libraries that these gems depend on are not available. Our attempt to install Nokogiri did not succeed due to a missing header file from Libxml2 library. Gem files will remain installed in C: /Ruby/22/lib/ruby/gems/2.2.0/gems/nokogiri-1.6.6.2 for inspection. Check the mkmf.log file for more details.

Installation will fail with quite a long message printed out in the Command Prompt. Just for illustration try to install Nokogiri from sources. Otherwise you can freely skip to the section “Installing Ruby On Rails”. If you want to know how to deal, at least partially, with such a libraries you should continue reading this chapter. Libxml2 is XML parser and toolkit written in C. Example of such a gem is Nokogiri, HTML and XML parser for Ruby, built upon Libxml2 library. Native gems might depend on other libraries which are hard, or sometimes, impossible to build on Windows. DevKit's smoke test passed without problems but does it really mean we can install any gem written in C/C++? Unfortunately the answer is no. Yet, problem of installing native gems requires a bit more of our attention and better explanation.
