Gem available in irb but not rails console

Question

I am trying to use the RedCloth gem in my rails project. When I used irb I can load the gem:

require 'rubygems'
require 'RedCloth'

and it works fine, but when I try the same thing in the rails console I get an error message stating that the gem cannot be found.

Does anyone have any idea what might cause this?

Answer 1

You can append gem path to ruby load path. Do this:

gem which faker
=> /usr/local/ruby/......../faker-0.1.1/lib/faker.rb

Start Rails console and do the following:

$: << '/usr/local/ruby/......../faker-0.1.1/lib/'

and now load faker gem

require 'faker'
=> true

Answer 2

Does your rails project's Gemfile include gem 'RedCloth' in it? Rails will only load the gems specified in that file.
