Dashing does not run on Heroku

623 views Asked by At

I'm trying to deploy Dashing to Heroku. Everthing runs perfectly on localhost. Deploying with the instructions provided by the github page

It seems to be something to be with the backports gem.

Below are the heroku log files

I fixed this by running:

bundle update backports

and making sure my Gemfile.lock was updated and committed.
