为什么Rails Console无法在带有Rails 3.1.3的ubuntu上启动

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.

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.
