How about updating Gemfile like this? It can make the error messages a bit simpler. It may be easier for users to pinpoint the cause of the problem.

[Before]

Bundler could not find compatible versions for gem "bundler":
  In Gemfile:
    rails (= 4.2.11) was resolved to 4.2.11, which depends on
      bundler (>= 1.3.0, < 2.0)

  Current Bundler version:
    bundler (2.0.1)
This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running `gem install bundler`?

Could not find gem 'bundler (>= 1.3.0, < 2.0)', which is required by gem 'rails
(= 4.2.11)', in any of the sources.

Bundler could not find compatible versions for gem "nokogiri":
  In Gemfile:
    nokogiri (~> 1.8.1)

    capybara (~> 2.13) was resolved to 2.18.0, which depends on
      nokogiri (>= 1.3.3)

    rails-dom-testing was resolved to 2.0.3, which depends on
      nokogiri (>= 1.6)

    roadie (~> 3.2.1) was resolved to 3.2.2, which depends on
      nokogiri (~> 1.5)

Bundler could not find compatible versions for gem "roadie":
  In Gemfile:
    roadie (~> 3.2.1)

    roadie-rails (~> 1.1.1) was resolved to 1.1.1, which depends on
      roadie (~> 3.1)

[After]

Bundler could not find compatible versions for gem "bundler":
  In Gemfile:
    bundler (>= 1.5.0, < 2.0.0)

  Current Bundler version:
    bundler (2.0.1)

Perhaps you need to update Bundler by running `gem install bundler`?

Could not find gem 'bundler (>= 1.5.0, < 2.0.0)' in any of the relevant sources:

I'm favour of this change. In which branches do you think to commit it?
