if you are blocked by this, npm -g i core-js will get the required dependencies installed. Ran into this on a clean box just now.

Getting the same issue here, installing core-js globally worked as @phil-scott-78 said.

This is an issue with apollo-upload-server 5.0.0 which uses some babel polyfill, but babel removed the dependency to core-js. This should be fixed in 6.0.0 once it gets stable and released in apollo-server, or if https://github.com/apollographql/apollo-server/issues/1536 is fixed we can just skip the whole module.

Just installed core-js globally and it worked. Thanks guys

[viztor]

it happened to us while using apollo as well. it is probably an independent from vue-cli. This issue should probably be in apollo-server-upload?

I did npm -g install core-js multiple times, but it did not work for me.
Turns out I'm using yarn for the project and yarn global add core-js did the trick for me.
Thanks @phil-scott-78

Use version 2.6.5 not 3.0.0
