Both environments are running 1.9.2-p290 ruby installed with RVM.</p> <p>When I run the following command I get the following problem:</p> <pre><code>[master][~/Sites/boss-mocha] bundle exec rake db:data:load --trace ** Invoke db:data:load (first_time) ** Invoke environment (first_time) ** Execute environment ** Execute db:data:load rake aborted!
