You are probably including ES-next version of swiper. If you use it with imports you need to use something like babel-loader or import correct version: import Swiper from 'swiper/dist/js/swiper.js';

I was using just import Swiper from 'swiper'; and I can confirm that import Swiper from 'swiper/dist/js/swiper.js'; solved the issue for me.

I got the same issue using Swiper 4 and I couldn’t figure out how to fix it. Using babel-loader throws this error:
