I have installed Ruby, RubyGems and then Jekyll, but when I run Jekyll I'm getting this error.

$ jekyll serve

Also if there is no way to fix it please help me if someone tells me how to completely remove Ruby, RubyGems Jekyll and fresh install it or fix this error.

I had the same error as you and after installing the JSON gem by sudo gem install json I had no problems. https://stackoverflow.com/questions/19788258/error-when-running-jekyll-new-command
