I am having a problem with my Travis build where the build fails with the error The command "bundle exec rake" exited with 1. Here is the build log from Travis. Here is a link to the GitHub repo.
I've tried adding require 'bundler' to my Rakefile as suggested by this question, but that didn't have any effect. I have no problems running bundle exec rake on my local machine and all tests are passing locally.
Here is the backtrace from Travis:

The command "bundle exec rake" exited with 1.
Any insight is greatly appreciated.
It turns out the problem was related to the username for the test database in my database.yml file. I opted to not set the username for the test database after looking at this SO question. The build is finally passing. Hopefully this helps someone in the future.
