Building native extensions. This could take a while... ERROR: Error installing nokogiri: ERROR: Failed to build gem native extension. /home/soichi/.rvm/rubies/ruby-1.9.3-p194/bin/ruby extconf.rb checking for libxml/parser.h... no ----- libxml2 is missing. please visit http://nokogiri.org/tutorials/installing_nokogiri.html for help with installing dependencies. ----- *** extconf.rb failed *** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options. But I have certainly installed libxml2, where I can check it with sudo apt-get install libxml2. Could anyone help me out here? It says, "Check the mkmf.log...", does anyone know where the file resides? soichi -- Posted via http://www.ruby-forum.com/.
