Support for loading ES Module in require() is an experimental

[gaborbernat]

I'm using React Router as a...

library

Reproduction

When using react-router-dom v7 I am getting:

CommonJS module react-router-dom/dist/index.js is loading ES Module node_modules/react-router/dist/development/dom-export.mjs using require().
Support for loading ES Module in require() is an experimental feature and might change at any time

You should be using the react-router package now, as per the upgrade instructions.
