I have the same err today, reason is import { reject } from "core-js/fn/promise", I delete it then app compiled successfully.

It works. In my case, VSCode automatically added the `import ...` line. – noobar Feb 22 '21 at 02:17

Try update your core-js dependency version by:

npm install core-js
// or
yarn add core-js

The error is a result of yourProject/node_modules/core-js is not sync with your code.

You're importing core-js/fn/promise, but the build tool not found it.

I had a similar problem with core-js when I tried to start a Vue app, this was the error:

core-js/modules/es6.array.find in ./src/state/helpers.js,
* core-js/modules/es6.function.name in ./node_modules/cache-loader/dist/cjs.js??ref--12-0!./node_modules/babel-loader/lib!./node_modules/cache-loader/dist/cjs.js??ref--0-0!./node_modules/vue-loader/lib??vue-loader-options!./src/components/_base-link.vue?vue&type=script&lang=js&, ./node_modules/cache-loader/dist/cjs.js??ref--12-0!./node_modules/babel-loader/lib!./node_modules/cache-loader/dist/cjs.js??ref--0-0!./node_modules/vue-loader/lib??vue-loader-options!./src/components/_base-icon.vue?vue&type=script&lang=js& and 4 others
...
..
..

my fix was to update dependencies and my package.json after the update is the next:

{
 ...
 "dependencies": {
  "core-js": "^2.6.12",
  "vue": "2.5.16"
 },
 "devDependencies": {
  "@babel/core": "^7.14.6",
 }
}

Do the following steps:

npm install name dependency,
npm install

It's perfectly running for me.
