i test your code and it works for me by the way i explain my steps for you, maybe you forget one step:

1. install package with npm install vue-qrcode-reader
2. make file named qr.js in my plugin folder
3. then put this code on it:

import Vue from 'vue'
import VueQrcodeReader from 'vue-qrcode-reader'

Vue.use(VueQrcodeReader)

4. add plugin to my nuxt.config.js file :

  plugins: ['~/plugins/qr']

NOTE:qr is the name of my file(qr.js)

5. use the plugin in my vue page with adding following code in it’s place:

<qrcode-stream></qrcode-stream>
<qrcode-drop-zone></qrcode-drop-zone>
<qrcode-capture></qrcode-capture>
