回答1:

I had recently encountered a similar error on Airflow 1.10.2 and in my case it was related to incorrect version of pendulum

Run pip show pendulum

Name: pendulum

Version: 1.4.4

Summary: Python datetimes made easy.

...
If your version of pendulum is different from v1.4.4 just do a force-reinstall (Airflow 1.10.2 requires pendulum===1.4.4)

pip install --force-reinstall pendulum===1.4.4

I didn't exactly solve the issue above, but just decided to switch to python3 and used pip3 install apache-airflow.
