What should I do?

which build you are using ?

[mallim]

using vue-burger-menu version 2.0.1

doing parcel serve for development

pointing to this
'''
main": "./dist/vue-burger-menu.common.js
'''

Well that's weird, can you try reproducing this issue on CodeSandbox ?

[mallim]

Not sure how CodeSandbox work with parceljs

Anyway, I got the files up on github https://github.com/mallim/vue-burger-menu-issue

just do

npx parcel index.html

Is it VueJS 2.6.0 problem or parceljs problem?

I think you might need Parcel source map loader - Please check this issue here - parcel-bundler/parcel#741
