Router module not found when using with Nuxt

[antiantivirus]

getting Cannot find module './router' error when trying to install on a nuxt project. Have setup a plugin in nuxt with the following code

import Vue from 'vue'
import router from './router'
import VueAnnouncer from '@vue-a11y/announcer'

Vue.use(VueAnnouncer, {}, router)

Any thoughts on a workaround or fix for this?
