When I try to build my VueJS typescript app I get the following dependency errors.

vue-cli-service serve

• 1 have you installed core-js? yarn add core-js - this is mostly used in polyfills and such – Michael Mano Commented Jul 2, 2019 at 1:55

npm add core-js did the trick for me :)

I've read several places that installing core-js will solve the problem, but installing that just by name will get you core-js@3 at the moment, and v3 is still only half baked and/or inpatible with the way that it's being used by the Vue CLI/Babel/Webpack tools. Specifically installing core-js@2 seems to fix the issue we're having. This is what got it the vue serve mand working for me again on new, as well as existing projects:

npm install --save-dev @vue/cli @vue/cli-service-global core-js@2

Good luck!
