I have rice gem (rice-1.1.0.gem) downloaded to my folder C:\Ruby19 I have tried the following at command prompt window to install rice. gem install rice However , I am getting the following error: << Building native extensions. This could take a while… ERROR: Error installing rice: ERROR: Failed to build gem native extension. C:/Ruby19/bin/ruby.exe extconf.rb Gem file will remain installed in C:/Ruby19/lib/ruby/gems/1.9.1/gems/rice-1.1.0 for inspection. Results logged to C:/Ruby19/lib/ruby/gems/1.9.1/gems/rice-1.1.0/gem_make.out << I think rice gem is not installed properly in my PC.I have tried calling require ‘mkmf-rice’ from the Interactive Ruby Window and it does not find the file.
