- Install homebrew.
brew install rbenv ruby-build
echo 'eval "$(rbenv init -)"' >> $HOME/.bash_profile
rbenv install 1.9.2-p290
rbenv global 1.9.2-p290
rbenv rehash
gem install bundler rails
That should do it. You should have a working Ruby 1.9.2 with latest bundler and rails gems installed.
rails new my-new-app
cd my-new-app
rails server
Congratulations! You have a new, empty app using SQLite. No more pushing to test!
