[Distutils] Fatal error "Python.h"

[Rick]

Hi
Can anyone help?
I’m pretty new to Python and Raspberry Pi.
When running PIP, I seem to get fatal error:

	Python.h: No such file or directory

	<hash>include “Python.h”

	compilation terminated

I get this when attempting to download both Cython and scikit-image.  So I’m assuming it is some absent file or path reference on the Raspberry Pi installation I have, rather than in the distribution package?

What is this file “Python.h” that it is trying to include?
