Superset Fresh Install or Upgrade results in TypeError

I have tried both upgrading from Superset 1.5 and installing Superset 2.0 in a separate pyenv. Both result in the same issue : TypeError: init() got an unexpected keyword argument ‘unbound_message’

How to reproduce the bug

1. I followed the https://superset.apache.org/docs/installation/installing-superset-from-scratch guide to setup 1.5 a few months ago and followed the same to setup 2.0. I also tried upgrading using https://superset.apache.org/docs/installation/upgrading-superset
2. Unable to run superset
3. Stack trace

OK, this is strange. When I installed I just used “pip install apache-superset”. The output of the superset --version command displays the following:

(superset2) [xxxxxxx ~]$ superset --version
Loaded your LOCAL configuration at [/home/xxxxxx/.superset/superset_config.py]
Python 3.9.11
Flask 2.2.0
Werkzeug 2.2.1

The requirements.txt points to Flask 2.0.3 and on a hunch I did a pip uninstall Flask and pip install flask==2.0.3. Also werkzeug==2.0.3 and jinja2==3.0.1

It now starts working. Wondering why pip install apache-superset installed newer versions of flask etc?

flask==2.0.3.,werkzeug==2.0.3, jinja2==3.0.1 and WTForms==2.3.3 worked for me.
