  <p>then I try follow this <a href="https://stackoverflow.com/a/47264220/6059754">ANSWER</a>, but showing this for me <code>find: convert: No such file or directory</code></p>
  
  <p>EDIT:</p>
  
  <p>I installed <code>imagemagick</code> using <code>npm install imagemagick</code> not <code>brew install imagemagick</code></p>
  
  <p>then running <code>find ./resources/ -name "*.png" -exec convert "{}" -alpha off "{}" \;</code> showing <code>find: convert: No such file or directory</code>.</p>
