<p>Unfortunately enabling the SenseHAT Sensor component for a Virtual Environment install of Home-Assistant fails with errors.
<em>(The Raspberry Pi All-In-One installer and HASSbian both run Home-Assistant in an virtual environment).</em>
These issues have been discussed in the repository issue (#5093)[https://github.com/home-assistant/home-assistant/issues/5093)</p>
<p>This fix has been tested with a clean install of:</p>
<ul>
<li><a href="https://downloads.raspberrypi.org/raspbian/images/raspbian-2017-01-10/">Raspbian Jessie - version January 2017</a></li>
