Answer 1

Sounds like you are running npx create-react-app command in a project that already includes react. Try running npm install instead.

If that does not work try to remove your node_modules folder and run npm install again.

Answer 2

You can try the following:

1. Delete both node_modules and package-lock.json
2. Run npm i web-vitals --save-dev
3. Run npm install
