Can't install package -- unable to resolve dependency tree (core-js)

When trying to run npm install @mathieustan/vue-datepicker --save I get following error in VUE-CLI console:

npm ERR! code ERESOLVE

Having the same issue - Is this package still being maintained?

Yeah, I am having this issue as well. Anybody found a fix? I want to use this picker as it's the only one I found which has quarter selection.

Seems to be blocked. No contribution on Github since December from the original author.
Looks like it's an abandonned project. Hope it is not ..
@mathieustan ?

Hello @oliviernguyenquoc.

I don’t have much time those days to work on it. I planned to do alot of improvements but I need more time.

Did you try to install core-js locally on your project ? (As a fix until I do something)

[oliviernguyenquoc]

Thanks for the answer. Totally understand (and good luck btw ;) )
If you can only test / merge this PR: #90
It should solve this installation issue.
