FirebaseUI Dependency Conflict

I am using FirebaseUI React Components ( to implement FirebaseUI Auth in a React app, which has previously worked without any issues. However, I recently upgraded Firebase to v9, and now when I try to install FirebaseUI React Components I receive a dependency conflict. Specifically, when I try:

npm install --save react-firebaseui

I receive the error:

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!
npm ERR! While resolving: project-js-frontend@0.1.0
npm ERR! Found: firebase@9.1.3

npm ERR!
npm ERR! Fix the upstream dependency conflict, or retry
npm ERR! this command with --force, or --legacy-peer-deps
npm ERR! to accept an incorrect (and potentially broken) dependency resolution.

Has anyone else working with FirebaseUI React Components, or FirebaseUI more broadly, encountered this error and found a solution? According to the Firebase docs, v9 is not compatible with FirebaseUI, and the issue I am encountering may be related to the issue here ( - however, if that's the case, is there any way to make FirebaseUI work after upgrading Firebase to v9?
