Dependabot can't resolve your Ruby dependency files

[dependabot-preview[bot]]

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 found conflicting requirements for the Ruby version:
  In Gemfile:
    Ruby (~> 2.1.10.0)

    spree_dev_tools was resolved to 0.1.8, which depends on
      Ruby (>= 2.3.0)

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.
