reinstall every thing like vue-cli node core-js but still have problem

remove npm and npm-cache

remove node_module in user/AppData/Roaming and reinstall every thing and still have problem

node v10.15.1
npm v6.4.1
vue v3.4.0

It’s a bug in apollo-env

@sodatea what should we do ?!

sadeghbarati on 2 Feb 2019

They depend on a beta version of core-js without locking its version.
And core-js’s directory structure just got changed due to the release of ES2019 standard.

Seems apollo-env has fixed this problem in https://github.com/apollographql/apollo-tooling/issues/962#issuecomment-460015427
Try npm i -g @vue/cli reinstall vue cli to update the dependencies, and vue ui work fine

After trying all the different solutions proposed above, it seems that removing the node_modules and then running npm build worked for me!
