Python: "pip install gmpy" on Windows 10 returns "cl.exe' failed with exit status 2"

I've installed Pyhton 3.7 on Windows10 and when I run pip install gmpy the console return me this error:

The error is in this line:

error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2019\\BuildTools\\VC\\Tools\\MSVC\\14.23.28105\\bin\\HostX86\\x64\\cl.exe' failed with exit status 2

Basically it means that Python needs cl.exe and it expect it at:

C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Tools\MSVC\14.23.28105\bin\Hostx86\x64

No problem, I go to the Environment Variable and i add that path both for my user and for the system:

Then I check if cl.exe is successfully in the path by typing cl in the terminal and it works:

enter image description here

But when I run again pip install gmpy I have the same error.

EDIT: I also tried with pip install gmpy2 and I receive the same error.

Where am I wrong?

Well the actual problem is that you are missing some header file gmp.h:

C:\Users\franc\AppData\Local\Temp\pip-install-du1j9u7s\gmpy\src\gmpy.h(30): fatal error C1083: Cannot open include file: 'gmp.h': No such file or directory

I suggest you try gmpy2, which is a newer version. It has wheels for Windows on PyPI but they are for older versions of Python unfortunately. Pre-built wheels for more recent Python versions are available here. The files are named after the Python version (e.g. cp37 for CPython 3.7) and architecture (e.g. amd64 for 64-bit)

A wheel can be installed like so:

pip install gmpy2‑2.0.8‑cp37‑cp37m‑win_amd64.whl
