title: Gem install rails doesn't work with Ruby 2.1.5 on Windows 7
body: <p>I have already tried the <code>gem install rails</code> on two different Windows 7 machines.
  Ruby version installed 2.1.5
  When I run <code>gem source</code> in command line I get <a href="https://rubygems.org" rel="nofollow">https://rubygems.org</a>
  But when I try to run <code>gem install rails</code> I get the following error:</p>
  
  <p>=================</p>
  
  <p>ERROR:  Could not find a valid gem 'rails' (>= 0), here is why:
            Unable to download data from <a href="https://rubygems.org/" rel="nofollow">https://rubygems.org/</a> - SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (<a href="https://api.rubygems.org/latest_specs.4.8.gz" rel="nofollow">https://api.rubygems.org/latest_specs.4.8.gz</a>)</p>
  
  <p>====================================================</p>
  
  <p>Is there a problem with the rubygems.org website ?</p>
  
  <p>Thanks.</p>
