Unable to resolve signature of class decorator when called as an expression.
  Type '<VC extends VueClass<Vue>>(target: VC) => VC' is not assignable to type 'typeof AkChatMessages'.
    Property 'extend' is missing in type '<VC extends VueClass<Vue>>(target: VC) => VC'

This error comes up with vue 3, to reduce the error to a warning you can do:

Change your shim according to this: https://github.com/vuejs/vue-next/issues/1072

Change your declaration to this:

import { Vue } from 'vue-class-component';
import { Prop } from 'vue-property-decorator';

export default class BaseComponent extends Vue {
  @Prop({ default: '' })
  msg!: string;
}

The issue still persists with vue: 2.5.18 and typescript: 3.2.2.
