Minikube install error with key for CLUSTER_PLATFORM

Most likely have done something obvious, but I do not know what to do!

Trying to get Big Data Cluster to work in Minikube, with big machine I have on Ubuntu 18 Desktop.
When running the mssqlctl command
pesmith@pesmith-HP-Z820-Workstation:~/.local/bin$ sudo ./mssqlctl cluster create --name "sqlbigdata"
[sudo] password for pesmith:

Do you accept the license terms? (y/n): y
NOTE: Cluster creation can take a significant amount of time depending on
configuration, network speed, and the number of nodes in the cluster.

Error processing command: "KeyError"
'CLUSTER_PLATFORM'

This was my lines in my .bashrc file that is setting the env vars

export ACCEPT_EULA="yes"
export CLUSTER_PLATFORM="minikube"

Any clues to the issue would be appreciated.

Commencez par reproduire la commande mssqlctl cluster create --name "sqlbigdata" dans Minikube sur Ubuntu 18, en utilisant les variables d’environnement indiquées dans .bashrc. Suivez l’endroit où la valeur de CLUSTER_PLATFORM est lue et déterminez ce qu’indique le KeyError ; le travail est terminé lorsque la création du cluster n’échoue plus à cette étape.
