Getting this error when running gulp perf-tool

This is my setup in my gulpfile.js

require('gulp').task('perf-tool', function () {
  var options = {
    siteURL:'website url',
    sitePages: ['/'],
    resultsFolder: './perf-tool'
  };
  return require('devbridge-perf-tool').performance(options);
});
