ImportError: cannot import name 'json' from 'itsdangerous'

When trying to use Flask, which pulls Version 2.1.0, we're seeing the following error:

File "/usr/local/lib/python3.8/site-packages/flask/init.py", line 21, in
from .app import Flask, Request, Response
File "/usr/local/lib/python3.8/site-packages/flask/app.py", line 25, in
from . import cli, json
File "/usr/local/lib/python3.8/site-packages/flask/json/init.py", line 21, in
from itsdangerous import json as _json
ImportError: cannot import name 'json' from 'itsdangerous' (/usr/local/lib/python3.8/site-packages/itsdangerous/init.py)

The program should correctly import the json library if its needed (which I believe it is) or it should be removed.

Environment:

• Python version: 3.8
• ItsDangerous version: 2.1.0
• Flask version: 1.0.2

You are using an unsupported version of Flask, please update to the latest version if possible. Additionally, please read https://hynek.me/articles/semver-will-not-save-you/, then use a tool like pip-tools to pin your dependencies and control when you get updates. Be sure to run your tests with deprecation warnings treated as errors so that you get notified of these types of changes early.

Just started looking into a more recent version of Flask. Thank you.
