When I tried to ,I got the below error:

Traceback (most recent call last):File "/home/stevenluk18/airflow/airflow_env/bin/airflow", line 5, in <module>from airflow.__main__ import mainFile "/home/stevenluk18/airflow/airflow_env/lib/python3.8/site-packages/airflow/__init__.py", line 34, in <module>from airflow import settingsFile "/home/stevenluk18/airflow/airflow_env/lib/python3.8/site-packages/airflow/settings.py", line 49, in <module>TIMEZONE = pendulum.tz.timezone('UTC')TypeError: 'module' object is not callable

• What's the problem? Please help!!!

When I try to , I got the TypeError. And I have try create the Linux Venv and activate with venv/bin/activate. I pip install the apache-airflow, still I can't call the package function. I used the <export AIRFLOW_HOME=pwd> command to locate the file that I'm working on and still not work.

And when I install the Airflow packages: python-nvd3, unicodecsv, google-re2.

Can't build wheel for these packages inside apache-airflow.

Will it affect the outcome?
