Rails Can't generate new project because of 'MAKE'
===

When I try to start a new rails project, I get stuck. It cry's for json 1.7.4. I'm on windows.

    rails new delete
          create
          create  README.rdoc
    .
    .
    .
             run  bundle install

    ms/json-1.7.4 for inspection.

    An error occured while installing json (1.7.4), and Bundler cannot continue.
    Make sure that `gem install json -v '1.7.4'` succeeds before bundling.

It drops the same error for gem install json -v '1.7.4' too.
What should I do?
