Cython and clang on mac, "Python.h not found"

Question

I'm running clang on mac to compile a c file created by running a very simple program through cython, but the compiler always give me a "Python.h not found" fatal error. I've tried every solution I could find, reinstalling python 3.9, using the -I/path/to/headerfile method, and rewriting the include statement in the code to contain the full filepath, but nothing has worked. When I do include the full filepath, I get fatal error: 'cpython/initconfig.h' file not found. What could the issue possibly be, and how would I fix it? The program itself works fine in the standard python interpreter, pyinstaller, and nuitka.

Answer 1

Installing Xcode (from the App Store) solved this for me on Mac.
