How to use the enzyme-adapter-react-15.4 function in enzyme-adapter-react-15

import { configure } from 'enzyme';

// enzyme requires special adapters now that are in different modules
// as opposed to different imports, so we need to configure it based on
// which React version we're testing
if (process.env.REACT_VERSION === '^15.4.0') {
  const Adapter = require('enzyme-adapter-react-15.4');
  configure({ adapter: new Adapter() });
} else if (process.env.REACT_VERSION === '<15.4.0 >15.0.0') {
  const Adapter = require('enzyme-adapter-react-15');
  configure({ adapter: new Adapter() });
} else {
  const Adapter = require('enzyme-adapter-react-16');
  configure({ adapter: new Adapter() });
}
