title: I can't upgrade pip: Could not fetch URL https://pypi.python.org/simple/pip/: There was a prόblem confirming the ssl certificate
body: <p>Trying to upgrade pip in my terminal. Here's my code:</p>
  
  <pre><code>(env) macbook-pro83:zappatest zorgan$ pip install --upgrade pip
  Could not fetch URL https://pypi.python.org/simple/pip/: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:645) - skipping
  Requirement already up-to-date: pip in ./env/lib/python3.5/site-packages
  You are using pip version 8.1.2, however version 10.0.1 is available.
  You should consider upgrading via the 'pip install --upgrade pip' command.
  </code></pre>
  
  <p>Any idea what the problem is? I also get the same error <code>There was a problem confirming the ssl certificate</code> when I perform <code>pip install django</code>.</p>
  
  <p><strong>Edit</strong> <code>pip install --upgrade pip -vvv returns</code>:</p>
