Dependency 'Requests' Fails in Python 3.6

Reproduce el fallo con install.sh --install-python3 --venv e inspecciona el bloque de configuración de bash de cyclecloud-gridengine alrededor de la línea 526 en specs/default/chef/site-cookbooks/gridengine/recipes/scheduler.rb. Comprueba cómo se selecciona la dependencia incluida Requests para Python 3.6. Se considera completado cuando el paquete se instala correctamente en Python 3.6.8 y el punto de entrada azge puede importar gridengine.

I am attempting to use the cyclecloud-gridengine 2.0.13 release on a RHEL 7.9 scheduler VM. The yum python3 package version for this Linux distribution is 3.6.8. I am running into errors in the jetpack deployment process with Python dependencies. You can recreate the issue by running the install.sh line out of the bash 'setup cyclecloud-gridengine' block in the scheduler.rb recipe. Below is the error that was encountered in chef-client.log:

My line 526 in scheduler.rb equates to line 488. I have added some logic higher up in the file to properly install epel-release for RHEL to fix the package install of jemalloc. The offending portion of the bash command is the install.sh. If you run that section at the command line you receive the same error:

Requests officially supports Python 3.7+.

From the requests github, python 3.6 support was dropped in release 2.28.0. Cyclecloud-gridengine 2.0.11 did not experience this problem as at the time the release package was built, requests was on version 2.26.0. When 2.0.13 was packaged as a fix for an autoscaling issue we experienced, requests version 2.28.1 was the latest available. I think one fix is to version pin the dependency for requests to <=2.27.1. Attached is a screen capture of the 2.0.11 package contents at left and the 2.0.13 contents at right.
