1. Activate your Skylab virtual environment, if you haven't already. 
   

   Code Block
   language shell
   source $JEDI_ROOT/venv/bin/activate

2. Force install cylc-flow. Note, cylc is installed in spack-stack but it has some compatibility issues so it is easiest at the point to re-install in your venv. 
   

   Code Block
   language shell
   pip install cylc-flow --force-reinstall

3. (*Optional - as needeed) rsync  is required for the workflow.  If a which rsync  does not return this application (if one is on a brand new OrbStack machine):
   

   Code Block
   language shell
   sudo su apt install -y rsync exit

4. Check cylc location and test with skylab/experiments/workflow-engine-test.yaml: 
   

   Code Block
   language shell
   which cylc create_experiment.py skylab/experiments/workflow-engine-test.yaml
