Re: How to change Apache Airflow Python path from Python 2.7 to 3?


This is a good case for using conda environments or virtualenv environments.

With conda you would create a new conda environment that uses python 3.6,
install your dependencies including airflow in that environment, then use
the airflow version in that environment.

To figure out the versions of python compatible with the conda recipes:
$ conda search airflow --channel conda-forge
Currently, 3.6 is the latest supported.

To create a conda environment with python 3.6 and install airflow from
conda-forge:
$ conda create --name=airflow --channel=conda-forge python=3.6 airflow

To enable that environment and run airflow, there are a few options.  Once
way is to activate the environment with the command then call airflow.
$ conda activate airflow
(airflow) $ airflow version
...

Another way is to call the airflow command with the full path.  This means
you don't have to activate the environment, just call the command in the
conda environment bin directory.
$ /anaconda3/envs/airflow/bin/airflow version
...


Good luck.

cheers,
Dennis
