When attempting to install the Ruby JSON gem on Windows you are most likely going to get an error similar to the below. The trick is to instead install json_pure gem using the syntax listed below the error.
Error:
C:>gem install json Building native extensions. This could take a while... ERROR: Error installing json: ERROR: Failed to build gem native extension. C:/ruby/bin/ruby.exe extconf.rb install json creating Makefile nmake 'nmake' is not recognized as an internal or external command, operable program or batch file. Gem files will remain installed in C:/ruby/lib/ruby/gems/1.8/gems/json-1.1.3 for inspection. Results logged to C:/ruby/lib/ruby/gems/1.8/gems/json-1.1.3/ext/json/ext/parser/gem_make.out
Install json_pure gem:
gem install json_pure
That should do it.
