p385 Upgrade

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.

gem install bundler rails ruby-debug19
rbenv rehash

echo "$(tput setaf 3)\n**NOTES**"
echo "You will still need to install bundler and the gems for each app in new gemsets."
echo "Inside each app root directory, run 'gem install bundler && bundle install'.$(tput sgr0)"

Paul, can you update the docs to also install "debugger" as a gem. I noticed that installing from bundler fails but installing manually was fine. It might just be a Gemfile.lock dependency that we need to bump up.

Script updated. Installing ruby-debug19 globally should generate the necessary files for our apps to bundle successfully out of the gate.

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