I tried to add factory_girl in Gemfile and execute bundle install --path vendor/bundle

I got another error :

Could not find gem 'factory_girl (~> 2.0.1, runtime)' in any of the gem sources listed in your Gemfile.

Here is the Gemfile:

source "http://rubygems.org"
gem "rails", "2.3.11"
gem "rack", "1.1.1"
gem "i18n", "0.4.2"
gem "rubytree"
gem "coderay",  "~> 0.9.7"
gem "mysql"
gem "factory_girl"

What should I do?

I think you need to use factory_girl version 1.2.4, so change this in your Gemfile:

gem 'factory_girl', '1.2.4'

This is on the README for version 1.3.3:

"If you want to use factory_girl with Rails versions prior to Rails 3, use version 1.2.4."
