Error installing json on windows 8.1

I have installed rails 4.2.3 and ruby 2.2.2p95 on windows 8.1 x64 . When I try to run "bundle install" the installation fails because of json -v 1.8.3. I already have json version 1.8.1 installed. When I run rubygems update command it does not get updated. If I try to individually run gem install json -v 1.8.3 or gem install json --platform=ruby --version=1.8.3 I get the following error.

ERROR:  While executing gem ... (OptionParser::InvalidArgument)
invalid argument: -platform=ruby

C:\>gem install json --platform=ruby --version=1.8.3

Try this gem install --verbose json -v 1.8.3. This should install the gem.

Looks like you might have the 32-bit DevKit installed instead. Try uninstalling the DevKit you have and downloading and re-installing the latest 64-bit one. For more detail check out this similar answer:
