This buildpack will install Ruby 1.9.3+ and will
use Bundler for dependency management. It will be used if
a Gemfile
is found.
The installed Ruby will be the same one that gets installed on Heroku's Cedar 14 stack with a fallback to a Ruby from the Cedar stack. By default Ruby 2.2.2 and Bundler 1.10.5 will be installed.
To specify a Ruby version, use the ruby
directive
of your project's Gemfile
, the DEVSTEP_RUBY_VERSION
environmental variable or
a .ruby-version
on you project's root.
To specify a Bundler version, use the the DEVSTEP_BUNDLER_VERSION
environmental
variable.
