core-js/modules/es.array.iterator dependency was not found

I try to use your plugin within Nuxt, but once I add it to my babel plugins I get an error:

 ERROR  Failed to compile with 1 errors

This dependency was not found:

* core-js/modules/es.array.iterator in ./.nuxt/router.js

To install it, you can run: npm install --save core-js/modules/es.array.iterato
r

I suppose it relates to the version of core-js. I'm using v.2.6.11 but your plugin seems to rely on v.3
Is it the case? If so - how can I use it with v.2 ?
