Note if you're using the react-router-dom package from react-router-4 you can handle this like so:

import { Router, Route } from 'react-router-dom';
import { createBrowserHistory } from 'history';

const history = createBrowserHistory();
const initGA = (history) => {
  (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
  (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
  m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
  })(window,document,'script','https://www.google-analytics.com/analytics.js','ga');

  ga('create', 'YOUR_IDENTIFIER_HERE', 'auto');
  ga('send', 'pageview');

  history.listen((location) => {
    console.log("tracking page view: " + location.pathname);
    ga('send', 'pageview', location.pathname);
  });
};

initGA(history);

class App extends Component { //eslint-disable-line
  render() {
    return
      (
         
         
       )
  }
}

Note that this requires you to install the history package (npm install history). This is already a dependency of react-router-dom so you're not adding any page weight here.

Also note: It is not possible to use the BrowserRouter component AND instrument your ga tracking this way. This is okay because the BrowserRouter component is just a really thin wrapper around the Router object. We recreate the BrowserRouter functionality here with where const history = createBrowserHistory();.
