I am new to ruby on rails. I finally succeeded installing rails on ubuntu 11 and created an app with "rails new myapp".
But while generating a model with "bundle exec rails generate model Comment user:string user_comment:text" i am getting the following error:
I am clueless for what might have went wrong.

You need to choose from that list of runtimes. The easiest I've found is therubyracer. Add this to your Gemfile, then do a bundle install
.
gem "therubyracer"
After that your model generator should work.
