get hacking!
 
ubuntu 8.04.0+ ; rubygems 1.3 ; rails 2.2.2 ~~>
 
 
First things first, you first need to upgrade the gems to 1.3 to install rails 2.2.2
 
sudo gem --version sudo gem update --system
 
1) When you see the error code: /usr/bin/gem:23: uninitialized constant Gem::GemRunner (NameError)
 
So the solution is to add require ‘rubygems/gem_runner’ line to /usr/bin/gem . If you don’t know how to do this or if you are a newbie, don’t worry, I am explaining it below .
 
Step 1 : Go to the terminal and type the following
 
$ cd /usr/bin/
 
This will move you to the folder /usr/bin/
 
Step 2 : Type the following command to open up file in text editor
 
$ sudo pico gem and enter your password
 
Step 3 : Add the line ‘rubygems/gem_runner’ to the gem file that opens up after Step 2 ,
 
Add the line before require ‘rubygems’ Step 4 : Press Ctrl+X to save the file and exit.
 
=====================================
 
 
 
If you are getting errors:
 
/usr/bin/gem:10:Warning: Gem::manage_gems is deprecated and will be removed on or after March 2009. /usr/bin/gem:23: uninitialized constant Gem::GemRunner (NameError)
 
Here's the hack:
 
sudo pico /usr/bin/gem
 
Change the top of the file to look like this:
 
require 'rubygems' require 'rubygems/gem_runner'
Gem.manage_gems
 
Then you could proceed to installing RAILS:
 
gem install rails
 
or
 
sudo gem install rails
 
=======================================
 
now we are ready to get ready.
 
1)download tarball
2)rake hackerfly:go
3)insert password for sudo if requested...
4)rake db:migrate
5)./script/server
