title: npm - tarball data for material-design-icons seems to be corrupted
body: <p>I'm having this error while running a <code>npm install material-design-icons@3.0.1</code>:</p>
  
  <pre><code>tarball data for material-design-icons@3.0.1 (sha1-mnHEh0chjrylHlGmbaaCA4zct78=) seems to be corrupted

  <p><a href="https://github.com/google/material-design-icons/issues/853" rel="noreferrer">Here</a> it's documented as a bug, but still without an answer nor a fix.</p>
  
  <p>I've tried to reinstall node, upgraded to latest npm version (currently running 6.4.1), did a <code>cache clean --force</code>, tried a <code>npm install --no-optional</code>, removed <code>package-lock.json</code>, removed <code>npm</code> &amp; <code>npm-cache</code> folders from AppData directory, running everything as Administrator, but still no luck.</p>
  
  <p>I even tried with material-design-icons@3.0.0 but the error remains.</p>
  
  <p>If I navigate to the folder that appears in the log (<code>node_modules\.staging\material-design-icons-7d5a1f73\action\drawable-xxhdpi</code>), it's empty, and is the only folder that exists in the entire node_modules directory. I can delete that dir without any problems, so it does not seem to be a permissions/lock issue. </p>
  
  <p>Any suggestions?</p>
