[Vuejs]-VeeValidate localization "Property 'locale' does not exist on type 'Validator'."

According to:
http://vee-validate.logaretm.com/localization.html#api

To dynamically change the locale in your component, you have to call localize like so

this.$validator.localize('fr', french)

And it should work just fine (you don’t need to call updateDictionary as the call above is already doing this)
