commuter: Unable to launch commuter

I am trying to set up commuter to work with an s3 storage backend on an Amazon EC2 instance.

Referencing the documentation at https://github.com/nteract/commuter I have set the relevant environment variables with the following commands:

export COMMUTER_STORAGE_BACKEND=s3
export COMMUTER_BUCKET=bucket-name

But when trying to launch commuter via commuter command I get the following error:

CONFIGURED DISCOVERY none
Running in the current working directory,  /home/jupyter-tljh_admin

    throw err;
    ^

Would love to get this set up, is this a reasonable place to ask for this sort of help? Thanks,
