EADDRINUSE when using with vue-cli-plugin-browser-extension

[leoplct]

I am using vue-cli-plugin-browser-extension

vue.config.js

const ExtensionReloader  = require('webpack-extension-reloader');

module.exports = {
  configureWebpack: {
    devtool: false,
    plugins: [
            new ExtensionReloader({
              port: 9090, // Which port use to create the server
              reloadPage: true, // Force the reload of the page also
              entries: { // The entries used for the content/background scripts or extension pages
                contentScript: ['detail-page', 'search-results'],
                background: 'background',
              }
            }),
          ]
  }
}

when I run vue-cli-service build --mode development --watch I get

Error: listen EADDRINUSE: address already in use :::9090
