Am not able to run rails server

The error that I get when I try to run this command is 

Could not find gem 'json (>= 1.8.0) ruby', which is required by gem 'uglifier (>= 1.3.0) ruby', in any of the sources.

I have been looking around for a solution and what I've come across is people saying to just run bundle install or bundle update but when I run bundle install or bundle update I get this error.

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

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 thought it might be helpful to point out that Im going through the one month rails trying to learn ruby on rails and don't know very much.

Perhaps this problem has to do with a recent update of XCode. After a XCode update you need to do the following steps:

  1. Open Xcode and accept the license agreement
  2. Reinstall the Command Line Tools.

The second step seems to depend on your OS versions. If xcode-select --install does not work try to start the Install Command Line Developer Tools app in /System/Library/CoreServices.

After reinstalling the Command Line Tools try to rerun bundle install.

Mavericks comes with ruby 2 preinstalled. Though you might tune the installation and install missing ruby-dev, I would highly recommend you to install ruby via rvm (preferred) or rbenv so you can manage multiple ruby versions and use gemsets.

Here is a good step-through explanation on how to do this.
