Unable to import the package through the Vue template.

[Shark-vil]

Hello. I have a problem. I use Electron in conjunction with Vue. I import the dependency in the template, but after compilation, various errors keep appearing. In the latest version of the "@xmcl/core" it gives an error with a cycle:

The template looks like this

I just started to master the library, so there is no complex code. It's all:

<template>
  <div id="main">
    <input v-model="username" type="text" />
    <input v-model="password" type="password" />
    <input v-on:click="playgame" type="button" value="Play" />
  </div>
</template>

<script>
    import { launch } from "@xmcl/core";

    export default {
      name: "home-page",
      data: {
        username: null,
        password: null
      },
      methods: {
        playgame () {
        console.log(launch);
        }
      }
    }
</script>

I have not found a topic with a similar problem, so I can assume that I am doing something wrong. Any suggestions?
