body: <p>i am using [Metronic v6.03]</p>
  
  <p>I followed the Quick Start  tutorial on documentation.
  <a href="https://keenthemes.com/metronic/?page=docs" rel="noreferrer">https://keenthemes.com/metronic/?page=docs</a></p>
  
  <p>If I give in the command ‘gulp build’ I get a message :</p>
  
  <p>“Replace Autoprefixer browsers option to Browserslist config.
  Use browserslist key in package.json or .browserslistrc file.</p>
  
  <p>Using browsers option cause some error. Browserslist config
  can be used for Babel, Autoprefixer, postcss-normalize and other tools.</p>
  
  <p>If you really need to use option, rename it to overrideBrowserslist.</p>

  <p>Gulb version</p>
  
  <p>CLI : 2.2.0</p>
  
  <p>Local version : 4.0.2</p>
  
  <p>I changed the line browserlist at package.json to</p>
  
  <p>"browserslist": [</p>
  
  <pre><code>"last 1 version",
  
  "&gt; 1%",
  
  "maintained node versions",
  
  "not dead"
  </code></pre>
  
  <p>]</p>
  
  <p>and try to replace the line with :</p>
  
  <p>"browserslist": [</p>
  
  <pre><code>"defaults"
  </code></pre>
  
  <p>]</p>
  
  <p>On Linux I added a file .browserslistrc with the lines above.</p>
