Error installing coreos/prometheus-operator and coreos/kube-prometheus

[deathemperor]

What did you do?
I ran

$ helm install coreos/prometheus-operator --name prometheus-operator --namespace monitoring
$ helm install coreos/kube-prometheus --name kube-prometheus --set global.rbacEnable=true --namespace monitoring

What did you expect to see?

• coreos/prometheus-operator and coreos/kube-prometheus is installed

What did you see instead? Under which circumstances?

Error: release kube-prometheus failed: namespaces "monitoring" is forbidden: User "system:serviceaccount:kube-system:default" cannot get namespaces in the namespace "monitoring"
