Installation issues using RailsApps composer tool for any example app

Question

I am using Ruby 2.2.2 & Rails 4.2.1, with RVM on Ubuntu 14.04 with node.js.

For any example app I attempt to create, I'm experiencing a recurrent error during the composer process. I suspect the issue is parsing the yaml file -- secrets.yml, but I see nothing unusual (compared to other rails apps). I've experimented with different app servers and explicitly naming secrets in devlopment.rb with no luck. I'd appreciate some direction to look next.

Answer 1

The issue had to do with pre-existing environment variables in .bashrc, although I am not clear what the problem was. I commented out those lines, which enabled composer to install the app properly. The format of those variables seem proper and had not caused issues in the past. It became clear there was a problem parsing Rails.appplication.secrets. I suspect a conflict when you have existing ENV and are using secrets.yml in development.
