The Engine Yard platform defaults to Bundler version 1.0.10, which throws the above error with newer versions of Rubygems. A common fix for this is to specify the Bundler version.
If the version of Bundler you’re using is 1.0.15, add this to your Gemfile
gem 'bundler', '1.0.15'
and then run
bundle update bundler
from the command line.
Common mistakes
- Make sure to specify
'1.0.15'
and not'~>1.0.15'
to ensure against future changes. - Run
bundle update bundler
from your local machine to create a new Gemfile.lock in your application. Otherwise this change won’t show up.
