title: No files matching the pattern .s?(c|a)ss" were found on Sage
body: <p>When I try to run Sage 9.0.10 in my Wordpress 5.5.3 theme and install Yarn and then do &quot;yarn build&quot; or &quot;yarn start&quot; I get this error:</p>
  <pre><code>PS C:\xampp\htdocs\patrick.visiegroep\wp-content\themes\visiegroep&gt; yarn build

  <p>With &quot;build&quot; and &quot;start&quot; always I get</p>
  <pre><code>Error: No files matching the pattern &quot;C:\xampp\htdocs\patrick.visiegroep\wp-content\themes\visiegroep\resources\assets\**\*.s?(c|a)ss&quot;
  </code></pre>
  <p>and I can't find what went wrong, because it used to work before I had to nuke my whole installment of Wordpress and Sage. After reinstalling this happens.</p>
