Getting the following error after running pip install airflow[postgres] command:

> raise RuntimeError("By default one of Airflow's dependencies installs

I am trying to install in Debian 9

So, did you set either SLUGIFY_USES_TEXT_UNIDECODE or AIRFLOW_GPL_UNIDECODE as stated in the message before installing? – tobi6
Yes I have tried that. I have exported those environment variable. – Md Sirajus Salayhin
Both? You should decide for one and set that. – tobi6

Try the following:

export AIRFLOW_GPL_UNIDECODE=yes

OR

export SLUGIFY_USES_TEXT_UNIDECODE=yes

Using export makes the environment variable available to all the subprocesses.

Also, make sure you are using pip install apache-airflow[postgres] and not pip install airflow[postgres]

Which should you use: if using AIRFLOW_GPL_UNIDECODE, airflow will install a dependency that is under GPL license, which means you won't be able to distribute your resulting application commercially. If that's a problem for you, go for SLUGIFY_USES_TEXT_UNIDECODE.

If you are installing using sudo run one of these commands:

sudo AIRFLOW_GPL_UNIDECODE=yes pip3 install apache-airflow

OR

sudo SLUGIFY_USES_TEXT_UNIDECODE=yes pip3 install apache-airflow

NOTE: If pip3 (python3) does not work for you, try pip command. The pip command can be pointing to python2 or python3 installation depending on your system. Verify this by running pip --version.

In case you are installing the airflow on Windows and through Python terminal then you need to write this:

Set SLUGIFY_USES_TEXT_UNIDECODE=yes

pip install apache-airflow[postgres]

It worked with me after I struggled with trying many other options. Hope this will work with you too.

Also, if you are installing using sudo you can use:

export AIRFLOW_GPL_UNIDECODE='yes'
sudo -E pip3 install apache-airflow

(or use SLUGIFY_USES_TEXT_UNIDECODE)
