title: pip: Install error with python2.7 on ec2 AMI
body: <p>After installing pip with get-pip.py </p>
  
  <pre><code> wget https://bootstrap.pypa.io/get-pip.py
   python get-pip.py
  </code></pre>
  
  <p>I get this error when I try to check the installation with <code>pip -V</code></p>

  <p>However this works with python2.6.</p>
  
  <p>Is there any reason why this happens that I am missing? </p>
  
  <h2>Edit:</h2>
  
  <p>I am working with Amazon Linux AMI release 2016.03 which I guess is based on some RedHat distro</p>
