Ruby `json` gem does not compile

I am trying to get Rails working on a Windows system. I installed RubyInstaller and the Devkit, but I cannot seem to get the json gem to install. When I try gem install json I get:

Building native extensions.  This could take a while...
ERROR:  Error installing json:
        ERROR: Failed to build gem native extension.

make: *** [generator.o] Error 1


Gem files will remain installed in C:/Ruby193/lib/ruby/gems/1.9.1/gems/json-1.8.3 for inspection.
Results logged to C:/Ruby193/lib/ruby/gems/1.9.1/gems/json-1.8.3/ext/json/ext/generator/gem_make.out

It could be my Ruby versions (I have both 2.2 and 1.9), but I do not know. What is going on?

After @Azolo posted his comment, I discovered that the DevKit version I was using did not match the Ruby version I was running. The problem came to be because I needed Ruby 1.9.3 on the path for the Heroku client to function, but was trying to use 2.2 DevKit (as I typically use Ruby 2.2 for development.
