title: Setting up Rails server
body: <p>I'm a beginner in Ruby, following "<a href="http://guides.rubyonrails.org/getting_started.html#creating-a-new-rails-project" rel="nofollow">Creating a New Rails Project</a>".</p>
  
  <p>But I can't start the server. I tried:</p>
  
  <ol>
  <li><p>running <code>rails server</code> but got:</p>
  
  <pre><code>Could not find gem 'tzinfo-data &lt;&gt;= 0&gt; x86-mingw32' in the gems available on the machine. 
  Run 'bundle install' to install missing gems.
  </code></pre></li>
  <li><p>running <code>bundle install</code> but got:</p>
  
  <pre><code>An error occurred while installing rake (10.4.2), and Bundler cannot continue.
  Make sure that 'gem install rake -v '10.4.2'' succeeds before bundling.
  </code></pre></li>
  <li><p><code>gem 'tzinfo-data'</code> but got:</p>
  
  <pre><code>Unknown command tzinfo-data
  </code></pre></li>
  <li><p><code>gem install tzinfo-data</code>:</p>
  
  <pre><code>Could not find a valid gem 'tzinfo-data' &lt;&gt;= 0&gt;, here is why:
  Unable to download data from...
  </code></pre></li>
  </ol>
  
  <p>I have Windows 8.1. 64-bit</p>
  
  <hr>
  
  <p><code>tzinfo-data</code> was resolved with a <code>cacert.pem</code> file following the guide in the accepted answer. Today I am trying to install <code>bootstrap-sass</code> gem file. Do I need an another .pem file?</p>
  
  <pre><code>Gem::RemoteFetcher::FetchError: SSL_connect returned=1 errno=0 state=SSLv3 read
  server certificate B: certificate verify failed (https://rubygems.org/gems/boots
  trap-sass-3.3.1.0.gem)
  An error occurred while installing bootstrap-sass (3.3.1.0), and Bundler cannot
  continue.
  Make sure that `gem install bootstrap-sass -v '3.3.1.0'` succeeds before
  bundling.
