"vue.use is not a function" fix

You should call vue.use() before vue object initialization (before calling new Vue({})), not after, and call it like static method, not instance method. For example:

import Vue from 'vue';
import App from "./App";
import * as VueWindow from '@hscmap/vue-window'

Vue.use(VueWindow);
let vue = new Vue({
    el: '#app',
    template: '<App></App>',
    render: h => h(App)
})
export {vue};
