On Ubuntu 21.04 with python 3.9, trying to install airflow. When I ran airflow init db command, below error is thrown
File "", line 855, in exec_module File "", line 228, in call_with_frames_removed File "/home/user/USB/.venv/lib/python3.9/site-packages/airflow/migrations/versions/82b7c48c147f_remove_can_read_permission_on_config.py", line 29, in from airflow.www.app import create_app File "/home/user/USB/.venv/lib/python3.9/site-packages/airflow/www/app.py", line 24, in from flask_appbuilder import SQLA File "/home/user/USB/.venv/lib/python3.9/site-packages/flask_appbuilder/init.py", line 6, in from .base import AppBuilder # noqa: F401 File "/home/user/USB//.venv/lib/python3.9/site-packages/flask_appbuilder/base.py", line 8, in from .api.manager import OpenApiManager File "/home/user/USB//.venv/lib/python3.9/site-packages/flask_appbuilder/api/manager.py", line 8, in from flask_appbuilder.baseviews import BaseView File "/home/user/USB//.venv/lib/python3.9/site-packages/flask_appbuilder/baseviews.py", line 21, in from .forms import GeneralModelConverter File "/home/user/USB//.venv/lib/python3.9/site-packages/flask_appbuilder/forms.py", line 16, in from .fields import EnumField, QuerySelectField, QuerySelectMultipleField File "/home/user/USB//.venv/lib/python3.9/site-packages/flask_appbuilder/fields.py", line 6, in from wtforms.compat import string_types, text_type
I tried installing wtforms separately.
airflow was installing with pipenv
Any idea?
thanks
