For example: + +.. code-block:: bash + + # Note: these instructions are for python3.7 but can be loosely modified for other versions + brew install [email protected] + virtualenv -p /usr/local/opt/[email protected]/Frameworks/Python.framework/Versions/3.7/bin/python3 .toy-venv + source .toy-venv/bin/activate + pip install apache-airflow + python + >>> import setproctitle + # Success! + +Alternatively, you can download and install Python directly from the `Python website <https://www.python.org/>`__.
