I'm trying to install gokogiri on Windows 8 machine, and these are steps that I have done so far :
Download
pkg-config_0.26-1_win32.zipfrom here, unzip/extract, and add thebinfolder topathenvironment variableDonwload
libxml2-2.9.2-win32-x86.7zfrom here, unzip to a location which path doesn't contain space(s) (otherwisegccwon't be able to find the location). Create new environment variablePKG_CONFIG_PATH, and add libxml's\lib\pkgconfigfolder location to the env variable.Donwload and install tdm64-gcc from here
run the following command (as suggested in the GitHub link above) :
go get github.com/moovweb/gokogiri
but then I get this error :

What is the error message complaining about now? If I need to download icnov manually, how then I put it together with libxml2 to work properly?
