Dependabot can't resolve your Ruby dependency files

[dependabot-preview]

Dependabot can't resolve your Ruby dependency files.

As a result, Dependabot couldn't update your dependencies.

The error Dependabot encountered was:

Bundler::VersionConflict with message: Bundler could not find compatible versions for gem "activerecord":
  In snapshot (Gemfile.lock):
    activerecord (= 3.2.11)

  In Gemfile:
    activerecord

    sinatra-activerecord (>= 1.2.1, <= 2.0.23) was resolved to 2.0.23, which depends on
      activerecord (>= 4.1)

Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.

Bundler could not find compatible versions for gem "coffee-script":
  In Gemfile:
    rack-coffee was resolved to 1.0.0, which depends on
      coffee-script

Could not find gem 'coffee-script', which is required by gem 'rack-coffee', in any of the sources.

If you think the above is an error on Dependabot's side please don't hesitate to get in touch - we'll do whatever we can to fix it.
