Ubuntu install rails 3 environment ================================================ 1) Get RVM installed with ruby 1.9.2 - http://www.christopherirish.com/2010/08/25/how-to-install-rvm-on-ubuntu-10-04/ 2) Install Rails 3 gem - gem install rails --no-rdoc --no-ri - .... Successfully installed rails-3.0.5 ... 23 gems installed 3) Install redcar 'ruby ide' - check out - http://azazeal.xelixis.net/post/How-to-install-Redcar-editor-under-Ubuntu-1010-with-RVM.aspx - for my situation I am only installing it on ruby 1.9.2, if you plan to run multiple versions of ruby this probably will not work when you have your rvm switched to another version - gem install redcar --no-rdoc --no-ri - redcar install - now you should be able to type redcar at the terminal to launch the gui - lets make a desktop shortcut - right click on the desktop : Create Launcher - Type: Application - Name: Redcar - Command: /home/YOUR_USER_NAME/.rvm/gems/ruby-1.9.2-head/gems/redcar-0.11/bin/redcar - Comment: Ruby IDE - need a tight icon for our launcher - right click > Properties > click the emblem icon - Path: /home/YOUR_USER_NAME/.rvm/gems/ruby-1.9.2-head/gems/redcar-0.11/share/icons/redcar-icon-beta.png - drag the desktop icon up to the launcher bar if you want one there as well - need to set the icon path again for that one 4) Create a rails application - mkdir projects; cd projects - rails new sample_app_01; cd sample_app_01 - in redcar > File > Open Directory > projects/sample_app_01 - ctrl+T > type Gem > open Gemfile - verify line : gem 'sqlite3' - back to the terminal - bundle - rails g scaffold post title:string body:text - rake db:migrate - rails s - in a browser go to http://localhost:3000/posts
