  <p>I am running on the command prompt as an admin and I am typing in <code>pip install pandas</code>. I have pip version 18.1. I have also tried running this on the Windows PowerShell within the scripts directory for python.</p>
  <p>I have never had an issue installing a package before.</p>
  <p>What is the error caused by and how do I fix it?</p>
