Error with yo aspnet

[joelmartinez]

Running through the Getting Started guide on the Mac ... unfortunately getting the following error when trying to run yo aspnet. Is the nuget executable being used something that was installed via the aspnet-generator, or something else on my system that might be out of date??

Actually, just realized I should probably have opened this issue here, which I've done :)
