[Vuejs]-Export "mdbDatePicker" was not found in "mdbvue"

You might have checked it, but it is a “PRO” component. If you are using the free version, you won’t be able to use it.

Something is seriously wrong with the “mdbVue” package.

I just tried following their documentation here

And even the first example isn’t working properly. It says errors for container,row and column components.

[Vue warn]: Unknown custom element: mdb-container – did you register
the component correctly? For recursive components, make sure to
provide the “name” option.

I would suggest you try using another library like Vuetify (based on material design as well), Buefy or just simple vue-bootstrap.

Apologies for not being able to help much.

Following this guide is helpful while having installation problems.
