I was trying to create a scratch org following the trailhead
I'm stuck in the following section Create and Test Our Scratch Org - Step 2
while executing the following command getting the following error.
sfdx force:org:create -s -f config/project-scratch-def.json -a dreamhouse-org
ERROR running force:org:create: Must pass a username and/or OAuth options when creating an AuthInfo instance.
