6 steps to set up a rails development environment on OS X:
- install Apple Command Line Tools
- install homebrew[1]:
/usr/bin/ruby -e "$(/usr/bin/curl -fksSL https://raw.github.com/mxcl/homebrew/master/Library/Contributions/install_homebrew.rb)"
- install rvm:
bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
- install ruby
rvm install 1.9.3
- install rails
gem i rails
- start a project
rails new myproject
[1] Use brew
command to install whatever database engine you need, ie brew install sqlite
Whilst ruby-1.9.3p125 will compile using llvm-gcc, there are plenty of common gems that rely on third party libraries that wont. Also the description for Rails.app talks about it being used by experienced developers - it's not intended to be just a mac version of railsinstaller.org.
