I have exact same errors with you.

no laravel mix.

I use vue2.

resolve it by reinstall vue-related packages like vue@legacy vue-demi @vue/composition-api @vueuse/core pinia vue-chartjs and ensure import the correct version. for example , use vue-chartjs in vue2, write
import { Bar } from 'vue-chartjs/legacy'
not
import { Bar } from 'vue-chartjs'

update vue-demi to the latest version

maybe you can del node_modules and *.lock file.
