  <p>My prettier configuration is:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>module.exports = {
    singleQuote: true,
    semi: false
  }</code></pre>
  </div>
  </div>
  </p>
  
  <p>Does anybody know what's the reason and how to fix?</p>
