the plug-in vuex-persist is used in the development to store the data in vuex to localStorage.

suddenly found that this plug-in will report an error in IE.

google said for a moment that the problem was caused by the failure to convert the ES6 syntax.

what can I do to make the code in this plug-in successful Babel

how to configure this item.

 build: {

    /*
    ** You can extend webpack config here
    */
    extend(config, ctx) {
      
    }
  }
