title: Errors when trying to start a new Rails app with Spree Commerce
body: <p>I am getting the following error when trying to install Spree Commerce (a clean install) into a new rails application. </p>
  
  <p>Could not load generator "generators/spree/install/install_generator". Error: uninitialized constant Bundler::Thor::Base.</p>
  
  <p>Any help would be greatly appreciated!  I have already checked the resources on the SpreeCommerce Documentation, Spree's Github, and similar issues that have come up and those solutions do not work for me.</p>
  
  <p>Edit:  Here is my gemfile:</p>
  
  <pre><code>source 'https://rubygems.org'

  <p>Here are the commands I have tried (all on clean new rails apps...all have the same resulting error as above):</p>
  
  <p>1)  I've tried using the methods listed on Spree's github page:</p>
  
  <pre><code>$ gem install spree
  $ rails _4.2.1_ new my_store
  $ spree install my_store
  </code></pre>
  
  <p>2)  I've tried adding spree gem manually to a new apps gemfile, and then:</p>
  
  <pre><code>$ bundle install
  $ rails g spree:install --sample=false --seed=false
  </code></pre>
  
  <p>3)  I've tried following the steps as outlined on the spreecommerce tutorial:</p>
  
  <pre><code>$ gem install spree_cmd
  $ rails new mystore
  $ spree install --auto-accept
  </code></pre>
