Answer 1

Below command should install apache-airflow and lets you pull changes into PyCharm for building DAGs and coding for Airflow.

SLUGIFY_USES_TEXT_UNIDECODE=yes

pip install apache-airflow

Answer 2

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.

Answer 3

Windows users can use the command below before installing apache-airflow:

$ set AIRFLOW_GPL_UNIDECODE=yes

then

$ pip install apache-airflow

Answer 4

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.

Answer 5

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)

Answer 6

Use below command to install apache-airflow

sudo SLUGIFY_USES_TEXT_UNIDECODE=yes \
pip install apache-airflow[async,devel,celery,crypto,druid,gcp_api,jdbc,hdfs,hive,kerberos,ldap,password,postgres,qds,rabbitmq,s3,samba,slack]
