title: Bundler could not find compatible versions for gem "bundler":
body: <p>Complete new person to Ruby and Rails here...  Have tried some tutorials in the past, but that's about it.  I'm trying to follow 'Ruby on Rails 3 Tutorial' book and have hit a roadblock that I haven't been able to find any help for after searching on here and the Google..</p>
  
  <p>I haven't actually done anything yet; only:</p>
  
  <pre><code>rails new first_app
  </code></pre>
  
  <p>then changed the Gemfile sqlite3 to</p>
  
  <pre><code>gem 'sqlite3-ruby', '1.2.5', :require =&gt; 'sqlite3'
  </code></pre>
  
  <p>When I run 'bundle install' I get the following:</p>
  
  <pre><code>Fetching gem metadata from http://rubygems.org/.........
  Bundler could not find compatible versions for gem "bundler":
    In Gemfile:
      rails (= 3.0.1) ruby depends on
        bundler (~&gt; 1.0.0) ruby
  
    Current Bundler version:
      bundler (1.1.3)
  
  This Gemfile requires a different version of Bundler.
  Perhaps you need to update Bundler by running `gem install bundler`?
  </code></pre>
  
  <p>I've tried uninstalling the bundler via</p>
  
  <pre><code>gem uninstall bundler -v 1.1.3
  </code></pre>
  
  <p>and then installing bundler v1.0.0 via</p>
  
  <pre><code>gem install bundler -v 1.0.0
  </code></pre>
  
  <p>but it seems to get me bundler 1.1.2..</p>
  
  <p>I just feel like I've hit a dead end and can't find any more information on how to solve this issue.</p>
  
  <p>Any help would be greatly appreciated and rewarded with copious amounts of bacon...</p>
  
  <p>UPDATE UPDATE UPDATE</p>
  
  <p>I couldn't get bundler v 1.1.2 to uninstall.  I finally was able to uninstall all of the gems by doing:</p>
  
  <pre><code>sudo gem list | cut -d" " -f1 &gt; gem_list.txt  
  cat gem_list.txt | xargs sudo gem uninstall -aIx  
  cat gem_list.txt | xargs sudo gem install
  </code></pre>
  
  <p>And then reinstalling...  This allowed me to then do the 'bundle install' and get on track..  Thank you all for your help!</p>
