(Use `node --trace-warnings ...` to show where the warning was created)
If you edit node_modules/iso-constants/index.js file like:
'use strict';
-module.exports = require('constants');
+const c = require('constants');
+module.exports = c;
and re-run the tests, stuff works fine and you get:
$ npm run test
> jest-reproduce-import-bug@1.0.0 test
> NODE_OPTIONS=--experimental-vm-modules node_modules/.bin/jest src/index.test.ts
