I get the following error when using eventbus

Uncaught TypeError: vue__WEBPACK_IMPORTED_MODULE_0__.default is not a constructor

this is main.js

import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
createApp(App).use(router).mount('#app')

this is EventBus.js

import Vue from "vue";
export const EventBus = new Vue();

I imported it:

import {EventBus} from '../assets/js/EventBus.js'

and i use it:

EventBus.$emit('increase-counter')
