Look for a python-dev or python-devel package.

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?

Others have answered the immediate question. But, in general, you'll probably want to install tools like Cython and scikit from the Raspberry Pi repositories directly (where they come prebuilt).

I don't have an RPi here, but try something like "sudo apt install cython scikit"
