title: pywifi can't be installed on python
body: <p>I tried to install pywifi through pip in python but the system says:</p>
  
  <blockquote>
    <p>You are using pip version 6.1.1, however version 10.0.1 is available.<br>
    You should consider upgrading via the 'pip install --upgrade pip'.<br>
    command. Collecting pywifi Could not find a version that satisfies the
    requirement pywifi (from versions: ) .<br>
    No matching distribution found for pywifi</p>
  </blockquote>
  
  <p>So I'm wondering how I should get it work?</p>
