A build of my project in TravisCI failed because Travis decided to use a version of Bundler (1.6.9, I think) that does not support blocks in
source , like this:
source 'https://rails-assets.org' do gem 'rails-assets-urijs' end
Without making any other changes, I re-launched the build, and there Travis used Bundler 1.11.2, which supports that feature, and everything worked fine.
So, how can I specify in my project the minimum version of Bundler that I want it to work with?
I think I've seen projects that list
bundler as dependency on their
Gemfile , but I'm not finding any references now.
