Description
On a Macbook 13inch without Xcode, I get the following error when I run yarn in tfjs-examples/mnist-node and tfjs-examples/baseball-node:

I think it means that XCode is required on Mac. If so, would be great to mention that in the docs, or try to detect it in a "preinstall" script and provide a nice user-friendly message.
