Cannot compile

[JakeSchoermer]

I followed the instructions that you set out in the README, but unfortunately the component did not compile.

I've added the terminal output below. I'm pretty new to the SP Framework, but it appears to be a problem in that layer.

I've tried this from scratch on two machines, one a Mac and one a PC with the same results.
