Setting up Rails on a Clean Install of Mac OS X Lion

I realise that OSX does not have a registry to clog up but I have just reinstalled Lion on my Macbook Air; probably a hang up from Windows. This is a checklist for installing Homebrew >> Rails.

  1. Install XCode 4.1 (There are issues with the 4.2 compiler and certain rubies and gems)
  2. Install Homebrew
    2. /usr/bin/ruby -e "$(curl -fsSL"
  3. Ensure Homebrew apps are in path before Mac apps
    1. export PATH=/usr/local/bin:$PATH or edit /etc/paths
  4. Install Git
    1. brew install git (thanks Brendan)
  5. Install SSH keys
    1. Generate or copy from ~/.ssh from a backup.
  6. Install RVM
    2. bash < <(curl -s )
    3. Add [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"  # This loads RVM into a shell session. to bash_profile
    4. Restart shell
    5. Run rvm | head -1
  7. Install latest Ruby and set as default
    1. rvm install 1.9.3 (make sure you are using Xcode 4.1)
    2. rvm --default use 1.9.3
  8. Install Rails
    1. gem install rails

I keep all my .config files in Dropbox and run a bash script to create aliases in my home folder.
