"Bundle Install" and "gem install json" notable to install

This is not an easy task to create an enviroment in our system.
This is output that I shared with you all.
Please help me out to solve the this problem.

=========================================================

  1. For Bundle installation I come up with some solutions are below.
    =========================================================
    bundle install --gemfile=TopSecret/weblog/Gemfile

Your user account isn’t allowed to install to the system RubyGems.
You can cancel this installation and run:

  bundle install --path vendor/bundle

to install the gems into ./vendor/bundle/, or you can enter your
password
and install the bundled gems to RubyGems using sudo.

An error occurred while installing json (1.8.6), and Bundler
cannot continue.
Make sure that gem install json -v '1.8.6' succeeds before
bundling.

===========================================================
2. Then i fired gem command for installing json then i got:-----------

/user# bundle install --gemfile=TopSecret/weblog/Gemfile
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
non-root users on this machine.
