It shows where the rake deploy task fails to run rake db:migrate on the heroku app, but doing the same command by hand works fine... Not sure what to do. Thought this was a heroku/therubyracer issue, but the actual git push deploy part works fine. It's the rake db:migrate part that fails...

By the way, I'm pretty sure you either have to have therubyracer installed, or as is our case, handlebars-rails

Oddly enough, it's failing locally, not on Heroku (that's why heroku run rake db:migrate ... works)

I suspect that #sh_heroku is trying to in the wrong bundle exec environment. (https://gist.github.com/joemsak/6d5c51805c2605ca5f4f#file-gistfile1-txt-L12)
