[REQUIRED] Step 2: Describe your environment

• Operating System version: MacOS 10.15.7
• Firebase SDK version: V6.0.0
• Firebase Product: app_check
• Python version: 3.7.9
• Pip version: 22.1.2

[REQUIRED] Step 3: Describe the problem

Updated to V6.0.0 and attempted to run my development server within Flask and encountered the following errors:

Error: While importing 'api', an ImportError was raised:

Traceback (most recent call last):
  File "/Users/kdfriedman/Desktop/curate-ai-python-api/env/lib/python3.7/site-packages/flask/cli.py", line 218, in locate_app
    __import__(module_name)

    from auth import validate_auth, validate_app
  File "/Users/kdfriedman/Desktop/curate-ai-python-api/api/auth.py", line 2, in <module>

    from firebase_admin import credentials, auth, firestore, app_check
  File "/Users/kdfriedman/Desktop/curate-ai-python-api/env/lib/python3.7/site-packages/firebase_admin/app_check.py", line 18, in <module>
    import jwt
ModuleNotFoundError: No module named 'jwt'

After attempting to install the jwt package to fix the issue, a new error occurred:

Error: While importing 'api', an ImportError was raised:

Traceback (most recent call last):
  File "/Users/kdfriedman/Desktop/curate-ai-python-api/env/lib/python3.7/site-packages/flask/cli.py", line 218, in locate_app
    __import__(module_name)

    from jwt import PyJWKClient, ExpiredSignatureError, InvalidTokenError
ImportError: cannot import name 'PyJWKClient' from 'jwt' (/Users/kdfriedman/Desktop/curate-ai-python-api/env/lib/python3.7/site-packages/jwt/__init__.py)

Steps to reproduce:

I updated to V6 of the SDK and immediately encountered this issue. When I attempted to install the jwt package, a different error occurred.

Relevant Code:

import firebase_admin
from firebase_admin import credentials, auth, firestore, app_check
import os

# Initialize the default app
ENV_KEYS = {
    "CREDS_GO_HERE"
}

CREDENTIALS = credentials.Certificate(ENV_KEYS)
firebase_app = firebase_admin.initialize_app(CREDENTIALS)

verify_app_token = app_check.verify_token

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hey @kdfriedman, Thank you for reporting this issue!
I think we need to add the new dependency to setup.py to include it in the final artifacts. I will submit a fix for this.
In the meantime, could you check installing the dependency pyjwt in your project would fix this issue?

pip install pyjwt[crypto]

Thanks!
