Ruby Rake - Error

Question

I am using vmware and trying to run rake db:migrate for getting the database tables. I am getting this error.

ubuntu@ubuntu-VirtualBox:~/hw-acceptance-unit-test-cycle/rottenpotatoes$ bundle exec rake db:migrate
rake aborted!
Bundler::GemRequireError: There was an error while trying to load the gem 'coffee-rails'.
Gem Load Error is: Could not find a JavaScript runtime. See     https://github.com/rails/execjs for a list of available runtimes.
Backtrace for gem load error is:

If you are on Linux then run:

sudo apt-get install nodejs

On Mac:

brew install node

and then run bundle and try to migrate. Must work. Also you shall be more attentive to the search on Stackoverflow for not to duplicate same topics. Rails - Could not find a JavaScript runtime?
