Re: [EXTERNAL] Re: First time Airflow install - uber fail

Hi,

RHEL 8 defaults to Python3(https://developers.redhat.com/blog/2018/11/14/python-in-rhel-8/) and carries through on Fedora’s python-  -> python2- package prefix fix.

Thus install dnf -y python3-devel

I will say, I find installing Airflow on python3 works fine and that is what we are running in production. Python 2.x will EOL sometime in the Spring (unless they push that deadline out AGAIN).

Thanks,

Mike

I'm not finding python-devel in any RHEL 8 repo.  If it's in a repo anywhere, I would not know how to find.

#dnf -y install python-devel
No match for argument: python-devel
Error: Unable to find a match: python-devel

You need to install Python header files:

On Ubuntu: sudo apt-get install python-dev.
On RedHat like distros it should be sudo yum install python-devel.

I followed the installation instructions exactly, what went wrong here?
