After configuring a Box app in my Box Dev console, installed the Box CLI tools and, following the steps in documentation, eventually get to the step where you enter the command:

box login -n BoxCLI

after which I’m prompted to enter the client id/secret for my app. After doing so I get the error “signalExit is not a function.” I’ve tried many variations of these steps and rebooted multiple times but always get this same error.
