Hi @metalsadman thanks for answering, After you mentioned if I had vuex in the project I search more than I had it installed but I was importing the function wrong import { ...mapGetters } from 'vuex'; I fixt the error by importing it right. thanks again and sorry

I solved it by adding plugins: ["@babel/plugin-transform-modules-commonjs"] to babel.config.js

For babel polyfill, just tamper with the .babelrc – mind that for v0.16+ u’re on Babel 7, not 6
