Airflow No module named 'wtforms.compat'

Question

recently i have been trying to install airflow on my Macbook pro( 2 GHz Quad-Core Intel Core i5)

However, i have been facing persistent problems in trying to create a virtual environment(venv) where i can install airflow.

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.9/bin/airflow", line 26, in <module>
    from airflow.bin.cli import CLIFactory
  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/airflow/bin/cli.py", line 82, in <module>
    from airflow.www.app import (cached_app, create_app)

    from airflow.www import utils as wwwutils

    from wtforms.compat import text_type
ModuleNotFoundError: No module named 'wtforms.compat'

System Description: 1.Macbook pro( 2 GHz Quad-Core Intel Core i5) 2.Python Version (3.8.12)

Possible solutions:

1. I have installed airflow in accordance to the documentation

   pip install "apache-airflow[celery]==2.2.3" --constraint "https://raw.githubusercontent.com/apache/airflow/constraints-2.2.3/constraints-3.8.txt"

2. I have tried most solutions here as well as airflow github issues. Most recommend reinstalling which i did as well. Some include changing wtforms == 2.3.3 but to no avail as well.

I have exhuasted most of my means i hope stackoverflow can guide me through this. Lastly, thank you in advance and i hope to learn from you

You are using Python 3.9 not python 3.8

  File "/Library/Frameworks/Python.framework/Versions/3.9/bin/airflow", line 26, in <module>

Apparently for some reason you mixed those. You should make sure you both CREATE and ACTIVATE virtualenv and install airflow in the right virtualenv.
