InstallError in Ruby on rails 3

I am getting the following error when i was trying to make one new app using Rails 3 and mysql.

I typed "rails new myapp -d mysql" and pressed on enter but the it displayed the below error.

Error:

Gem::InstallError: execjs requires Ruby version >= 2.0.0.
An error occurred while installing execjs (2.5.1), and Bundler cannot continue.
Make sure that `gem install execjs -v '2.5.1'` succeeds before bundling.

Please help me to resolve this error and make a new project with mysql successfully.I am using rails version 3.2.19 and ruby 1.9.3.
