You are using the wrong version of cocaine. Run bundle install then make sure you are using bundle exec rails s to start your rails server.

The run method in the newer version of cocaine (~> 0.4.0) takes an optional argument (def run(interpolations = {})) that the older version (0.3.2) didn't.

See comments above.
