p385 Upgrade
Raw
README.md

Assumption

You installed rbenv and ruby-build via homebrew.

Simple Upgrade

  1. Open a terminal.
  2. curl https://gist.github.com/prsimp/4773603/raw/upgrade_385.sh | sh
  3. Drink some coffee or do something while Ruby compiles.
  4. Profit!

Troubleshooting

  • If you see an error from homebrew complaining about "untracked working files" run this command:
    cd $(brew --repository) && git fetch origin && git reset --hard origin/master && cd -

What the heck is this doing?

  1. Updates your homebrew formulae
  2. Upgrades rbenv to 0.4.0 if you haven't already.
  3. Upgrades ruby-build if you haven't already.
  4. Installs ruby 1.9.3p385 and sets it as your default global Ruby (aren't we presumptious!)
  5. Installs the bundler and rails gems globally.
  6. Prints a message about making sure to install bundler and bundle for all apps.

Ken had trouble with p385 installing and we got it fixed by first running export CC=gcc. Found from stackoverflow
