Failed to Resolve Directive

[jamespurnama1]

This module used to work but somehow stopped working. Running Vue 2.6.12. I have tried importing it in the child component & importing it like so:
import VueHotkey from 'v-hotkey/dist/v-hotkey.umd' but it still did not work.

Here is a simple setup of my project which includes another Vue module:
Child.vue

<template>
    <div v-hotkey="keymap" v-touch:swipe="swipe">
     // some divs
    </div> 
</template>
<script>
export default {
  computed: {
    keymap () {
      return {
        up: this.goPrev,
        down: this.goNext,
// ...
};
</script>

main.js

import Vue2TouchEvents from 'vue2-touch-events';
import VueHotkey from 'v-hotkey';

Vue.use(Vue2TouchEvents)
   .use(VueHotkey);

Did I do something wrong? Or is there a bug like these other modules' (1) (2) (3) git issue?
