Airflow Solutions
Solution 1 - Airflow
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.
Solution 2 - Airflow
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
.
Solution 3 - Airflow
Windows users can use the command below before installing apache-airflow:
$ set AIRFLOW_GPL_UNIDECODE=yes
then
$ pip install apache-airflow
Solution 4 - Airflow
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
Solution 5 - Airflow
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.
Solution 6 - Airflow
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
)
Solution 7 - Airflow
Run the following command in your python terminal: SLUGIFY_USES_TEXT_UNIDECODE=yes pip install apache-airflow==1.10.0
Solution 8 - Airflow
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]
