Cannot setup swiftly in a VM

I'm running a Tart.app vm (Tahoe host & guest) and trying to install swiftly, however I get a rather inscrutable error when I try: ``` $ swiftly init --assume-yes --no-modify-profile Creating shell environment file for the user... Fetching the latest stable Swift release...
