I have been facing a weird error which is that I cannot import firebase, I tried compat, re-installing, etc.

If you know about it, please help me...

import firebase from 'firebase';
//import * as firebase from 'firebase/app';
//import firebase from 'firebase/app';

all of above does not work

the error is Module not found: Can't resolve 'firebase'

my firebase version is 9.1.2
