Upgrading Ruby

"If something is painful, do it more often."

  • 2.1.5: Nov 13 2014

OS X

I am using chruby and ruby-install.

ruby-install ruby ruby-2.1.5
chruby 2.1.5

Don't forget you're basically starting from scratch here. All of your 'global' gems will be gone now. At the very least, do:

gem install bundler

You can clean up old rubies in ~/.rubies.

Updating ruby applications

Edit the ruby version hints in the following files:

  • .ruby-version
  • Gemfile

Run bundle. Since gems belong to a specific ruby version, they all have to be re-downloaded (ugh).

Updating servers built with ansible

For servers built via jbinto/ubuntu-ansible-rails-server, edit the following files:

  • vars/defaults.yml

Run ag 2.1.3 (or the current version number) to double check.

Re-deploy your applications with hints to use 2.1.5.

You will have to restart nginx manually via ssh (TODO FIXME).
