Don’t run Bundler as root. Bundler can ask for sudo if it is needed, and
installing your bundle as root will break this application for all

An error occurred while installing json (1.8.1), and Bundler cannot
continue.
Make sure that gem install json -v '1.8.1' succeeds before bundling.

i am using ruby on windows 7 64bit
plz help me

It looks like the gem you want to install uses the json gem, and when
bundler tried to install the json gem, it couldn’t. Did you
subsequently try doing this:

download the DevKit
from ‘Downloads’ and follow the instructions
at 'Home · oneclick/rubyinstaller Wiki · GitHub
