I have been trying to install Apache Airflow on my local Mac machine for weeks. No tutorial have been helpful, I’ve been literally reading the Airflow website docs through and through, copying step by step processes, used Claude and ChatGPT but I don’t seem to get it running.

When I run any airflow commands such as airflow standalone or airflow db init, I get the following error:

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.12/lib/python3.12/site-packages/airflow/settings.py", line 55, in <module>
    TIMEZONE = pendulum.tz.timezone(tz)
               ^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: 'module' object is not callable

During handling of the above exception, another exception occurred:

I have created a python environment using python -m venv venv command and installed the following dependencies:

AIRFLOW_VERSION=2.10.0

# Extract the version of Python you have installed. If you're currently using a Python version that is not supported by Airflow, you may want to set this manually.
# See above for supported versions.
PYTHON_VERSION="$(python -c 'import sys; print(f"{sys.version_info.major}.{sys.version_info.minor}")')"

CONSTRAINT_URL="https://raw.githubusercontent.com/apache/airflow/constraints-${AIRFLOW_VERSION}/constraints-${PYTHON_VERSION}.txt"
# For example this would install 2.10.0 with python 3.8: https://raw.githubusercontent.com/apache/airflow/constraints-2.10.0/constraints-3.8.txt

pip install "apache-airflow==${AIRFLOW_VERSION}" --constraint "${CONSTRAINT_URL}"

I’ve changed it to my Python version 12.0 (which is compatible with Airflow.

I’ve also tried to install pendulum package as it seems like what it’s needed but it’s still giving the same error output.

Please help, I beg you, I’ve been struggling immensively with this. I really need to get an Airflow application running and it’s just looking impossible.
