sudo-apt get install curl
install RVM based on instructions on RVM web site:
curl -L https://get.rvm.io | bash -s stable --ruby
open new terminal window / shell for RVM to take effect let RVM tell you what else you need to install:
rvm requirements
based on what rvm requirements said, I installed:
sudo apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion pkg-config
reinstall ruby and set it up
rvm reinstall 1.9.3
rvm gemset create todo
rvm use 1.9.3@todo --default
gem install rails --no-rdoc --no-ri
make sure you have the right ruby and the right rails:
$ ruby --version
ruby 1.9.3p194 (2012-04-20 revision 35410) [i686-linux]
$ rails --version
Rails 3.2.8
thats it! You should be able to create a new rails app and run it
rails new todo
cd todo
workaround some wierd latest rails bug by adding this line to Gemfile
gem 'therubyracer'
rerun bundler
bundle
generate a scaffold
rails g scaffold task name:string due_date:datetime completed:boolean
launch rails server
