在Windows上安装Nokogiri gem

Question

I'm trying to install Ruby on my Windows environment. It works fine on my Ubuntu.

I followed the instructions here: https://github.com/oneclick/rubyinstaller/wiki/Development-Kit

Ruby 2.0 seems to be correctly set, both DevKit and RubyInstaller.

But when I try to bundle ig Get the following:

gem install nokogiri -v '1.5.11'
Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing nokogiri:
        ERROR: Failed to build gem native extension.

    C:/Ruby/RubyInstaller200-x64/bin/ruby.exe extconf.rb

Gem files will remain installed in C:/Ruby/RubyInstaller200-x64/lib/ruby/gems/2.0.0/gems/nokogiri-1.5.11 for inspection.
Results logged to C:/Ruby/RubyInstaller200-x64/lib/ruby/gems/2.0.0/gems/nokogiri-1.5.11/ext/nokogiri/gem_make.out

I already have this gem installed, but in another version.

C:\wamp\www\holdsport>gem list | grep noko              
nokogiri (1.6.2.1 x64-mingw32)

It seems like libxml2 isn't installed but I couldn't find out how install it on windows. I don't know if the message extconf.rb failed is because the libxml2 is missing or another issue.

Any idea why it doesn't work?

Nokogiri doesn't support x64 ruby 2.0, for whatever reason. Try installing the x86 version of ruby instead.

If gem install nokogiri still doesn't work, install the pre-release with gem install nokogiri --pre .
