Running start_vagrant_celery.sh issues error No module named 'config'

[Blank-Man]

(metta) ➜ metta git:(master) ✗ ./start_vagrant_celery.sh Usage: celery [OPTIONS] COMMAND [ARGS]...

Error: Invalid value for '-A' / '--app': No module named 'config'
(metta) ➜ metta git:(master) ✗

I believe I have followed setup instructions but something has caused it to error in a weird way.
