  <p>Any ideas what I'm doing wrong? I did research the topic and found some chat on github about the Python 3 extension but it covers a different error message.</p>
  
  <p>Edit:
  I have run <strong>sudo apt-get install libcwiid1 libcwiid1-dev</strong> before the pip command but got the following error message</p>
  
  <pre><code>Reading package lists... Done
  Building dependency tree       
  Reading state information... Done
  Package libcwiid1-dev is not available, but is referred to by another package.
  This may mean that the package is missing, has been obsoleted, or
  is only available from another source
  However the following packages replace it:
    libcwiid-dev
  
  E: Package 'libcwiid1-dev' has no installation candidate

  <p>I assume this is were the original problem comes from?</p>
