Hello, when doing the 
Get Started with Salesforce DX 
Quick Start: Salesforce DX 
Create and Test Our Scratch Org

I get the ERROR:  ts_types_1.definiteEntriesOf is not a function.
I have Dev hub enabled, and followed all ths steps.
I am running the 
sfdx force:org:create -s -f config\project-scratch-def.json -a dreamhouse-org

Has anyone encountered this error before and the error message is not exactly clear on what could be the issue.
