Seem that you need to add(install) firebase admin SDK (which include python modules) to your project:
Add SDK
$ sudo pip install firebase-admin
and then initialize it with npm:
Add Firebase SDKs and initialize Firebase
Install the Firebase JavaScript SDK:
a. If you don't already have a package.json file, create one by running the following command from the root of your JavaScript project:
npm init
b. Install the firebase npm package and save it to your package.json file by running:
npm install --save firebase
the link refer to several other configuration that you may need to double check about how to create the firebase project and its configurations.
