Elixir Nerves Phoenix Umbrella Project Error upon running

Question

So, I tried following this Nerves Tutorial , just for fun, to set up a phoenix-framework, this error gets thrown at me at the end of the tutorial when trying to run the server.

cjsMBP15:ui cj$ mix phoenix.server
==> fs (compile)
Compiling c_src/mac/cli.c

I have recompiled, cleaned, updated fs library, but cannot simply seem to get it to run. 

Can anyone point out where have I made a mistake?

Thanks.

IMO, you are experiencing is an issue compiling: fs for Mac OS. Try updating your brew and ensuring that you have Xcode installed.
