Why rails console did not fire up on ubuntu with rails 3.1.3

Question

When type rails console under the deploy subdir on ubuntu, instead of firing up the console, it displays help message for rails:

Usage:
  rails new APP_PATH [options]

Options:
  -r, [--ruby=PATH]              # Path to the Ruby binary of your choice

However irb can fire up without error. Anyone knows why? Thanks so much.

Do a rails -v. I bet you're not actually running 3.1.3 from the console. — rwilliams, Mar 03 '12 at 05:25
rails -v return 3.2.2. After bundle install, it show 3.1.3. thanks. — user938363, Mar 03 '12 at 05:44

Check this answer here: typing 'rails console' doesn't start?

You need to make sure that your current directory is the base directory of a rails app, because the rails console command needs to load the environment of that app.

I am in root. Now it return error saying js runtime could not be found. – user938363 Mar 03 '12 at 05:46
Rails cannot find a proper JavaScript runtime, so you need to add one to the Gemfile in your project root. Append `gem 'execjs'` and `gem 'therubyracer'` to your Gemfile and run `bundle install` in the root of the app. – Rick Button Mar 03 '12 at 05:48
