bootstrap is depending on the deprecated popper, so you'll have to keep it if you want to use bootstrap. – Exempt

Answer 2

This isn't necessarily a problem, unless you are wanting to upgrade from the deprecated version.

If you wish to upgrade, just run npm install @popperjs/core --save and then npm uninstall popper.js --save from within your project directory to install Popper v2 and uninstall the deprecated version.
