While upgrading a Discourse install on ubuntu 12.10, I get this:

# bundle install --without test --deployment

Gem files will remain installed in /opt/bitnami/apps/discourse/htdocs/vendor/bundle/ruby/1.9.1/gems/therubyracer-0.12.0 for inspection.

An error occurred while installing therubyracer (0.12.0), and Bundler cannot continue.
Make sure that `gem install therubyracer -v '0.12.0'` succeeds before bundling.

After doing a 'bundle exec gem install therubyracer -v 0.12.0' (which worked!), blowing away vendor/gems, and rerunning the bundle install, it installed just fine.

Not sure if I cleaned up old files hanging around somewhere.

This should be closed, then.

I'm getting this exact issue on a clean install, Ubuntu 12.10, ruby 2.2.2. uninstalling and reinstalling is doing nothing for me, for all versions 0.12.x.

Ubuntu 12.10 is EOL
