title: How can I resolve these Rails gem dependecies after adding rmre 0.0.4?
body: <p>I made a new rails 3.2.8 app and added:  </p>
  
  <pre><code>gem "rmre", "~&gt; 0.0.4"
  </code></pre>
  
  <p>to this new gemfile:</p>
  
  <pre><code>source 'https://rubygems.org'
  
  gem 'rails', '3.2.8'
  
  # Bundle edge Rails instead:
  # gem 'rails', :git =&gt; 'git://github.com/rails/rails.git'
  
  gem 'mysql2'
  
  
  # Gems used only for assets and not required
  # in production environments by default.
  group :assets do
    gem 'sass-rails',   '~&gt; 3.2.3'
    gem 'coffee-rails', '~&gt; 3.2.1'
  
    # See https://github.com/sstephenson/execjs#readme for more supported runtimes
    # gem 'therubyracer', :platforms =&gt; :ruby
  
    gem 'uglifier', '&gt;= 1.0.3'
  end
  
  gem 'jquery-rails'
  
  gem "rmre", "~&gt; 0.0.4"
  
  # To use ActiveModel has_secure_password
  # gem 'bcrypt-ruby', '~&gt; 3.0.0'
  
  # To use Jbuilder templates for JSON
  # gem 'jbuilder'
  
  # Use unicorn as the app server
  # gem 'unicorn'
  
  # Deploy with Capistrano
  # gem 'capistrano'
  
  # To use debugger
  # gem 'debugger'
  </code></pre>
  
  <p>Running bundle install yields:</p>
  
  <pre><code>Bundler could not find compatible versions for gem "erubis":
    In Gemfile:
      rmre (~&gt; 0.0.4) ruby depends on
        erubis (~&gt; 2.6.6) ruby
  
      rails (= 3.2.8) ruby depends on
        erubis (2.7.0)
  </code></pre>
  
  <p>I tried commenting out the version numbers and even removing the gems related to asset management.  Still, I can't seem to arrive at a combination of gem versions that work here.  It's the first time I've run into this sort of situation and I am not sure what else I might do to try out the rmre gem with a version of rails that is at least 3-point-something.</p>
  
  <p>Is there a clever way to search for a workable dependency resolution here?  If there is not a gem version configuration that meets the recommended dependencies, is there a least-bad approach to pursue?</p>
  
  <p>Many thanks!</p>
