title: Problem launching Rails server
body: <p>Just started up in Rails. I'm on windows vista, installed the latest build of ruby from <a href="http://rubyinstaller.org/" rel="nofollow">http://rubyinstaller.org/</a> and everything went well.</p>
  
  <pre><code>ruby -v
  ruby 1.9.2p290 (2011-07-09) [i386-mingw32]
  </code></pre>
  
  <p>I run:</p>
  
  <pre><code>gem update --system
  gem sources -a http://gemcutter.org
  gem install rails
  </code></pre>
  
  <p>No errors reported.</p>
  
  <pre><code>rails --v
  Rails 3.1.0
  </code></pre>
  
  <p>after this I created a folder for my Rails project and I created a new Rails app inside  as follows:</p>
  
  <pre><code>rails new test
  cd test
  bundle install
  </code></pre>
  
  <p>(again no error reported)</p>
  
  <p>But when I run <code>rails server</code> I get this error:</p>
  
  <pre><code>rails server
  ←[31mCould not find rails-3.1.0 in any of the sources←[
  ←[33mRun `bundle install` to install missing gems.←[0m
  </code></pre>
  
  <p>I try to run bundle again but no success again... After this, if I type again rails -v I get the same error as before. I have to close the windows console and reopen for rails -v to start working again!!</p>
  
  <p>Has anyone experience this?! Can you help?</p>
  
  <p>Thanks!!!</p>
  
  <p>As requested the gemfile content is:</p>
  
  <pre><code>source 'http://rubygems.org'
  
  gem 'rails', '3.1.0'
  
  # Bundle edge Rails instead:
  # gem 'rails',     :git =&gt; 'git://github.com/rails/rails.git'
  
  gem 'sqlite3'
  
  
  # Gems used only for assets and not required
  # in production environments by default.
  group :assets do
    gem 'sass-rails', "  ~&gt; 3.1.0"
    gem 'coffee-rails', "~&gt; 3.1.0"
    gem 'uglifier'
  end
  
  gem 'jquery-rails'
  
  # Use unicorn as the web server
  # gem 'unicorn'
  
  # Deploy with Capistrano
  # gem 'capistrano'
  
  # To use debugger
  # gem 'ruby-debug19', :require =&gt; 'ruby-debug'
  
  group :test do
    # Pretty printed test output
    gem 'turn', :require =&gt; false
  end
