Vue 2.5 vue-class-component uses Vue namespace but it's a Type

Question

After upgrading my Vue 2.0 Typescript project that uses vue-class-component to Vue 2.5, I get the following error in the declaration file:

ERROR in /myproject/node_modules/vue-class-component/lib/declarations.d.ts

(6,33): error TS2702: 'Vue' only refers to a type, 
but is being used as a namespace here.

Indeed, the declaration.d.ts seems to use Vue as a namespace:

options: Vue.ComponentOptions<Vue>

But how can I fix this? Is this an oversight/glitch in the declaration file of vue-class-component?

The whole declaration file:

import Vue from 'vue';
export declare type VueClass = {
    new (): Vue;
} & typeof Vue;
export declare type DecoratedClass = VueClass & {
    __decorators__?: ((options: Vue.ComponentOptions<Vue>) => void)[];
};

I fixed it by importing componentoptions explicitly, this seems to work:

import Vue from 'vue';
import {ComponentOptions} from 'vue'

let options : ComponentOptions<Vue>;

Vue's declaration files recently updated, so make sure both vue-class-component and vue are up-to-date. Because of the update, you may have to reference types in the following way:

import Vue, * as VueTypes from "vue"

let x: VueTypes.ComponentOptions<any>;
