C:\\Program Files (x86)\\Microsoft Visual Studio\\2019\\BuildTools\\VC\\Tools\\MSVC\\14.29.30133\\bin\\HostX86\\x86\\cl.exe' failed with exit status 2

Question

I am trying to pack py code with cython, however when I am running python setup.py build_ext --inplace, command prompt shows:

Anaconda3\include\pyconfig.h(59): fatal error C1083: Cannot open include file: 'io.h': No such file or directory
error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2019\\BuildTools\\VC\\Tools\\MSVC\\14.29.30133\\bin\\HostX86\\x86\\cl.exe' failed with exit status 2

I do have Visual Studio(2017 and 2019) and Build Tools as well; In the command prompt I did:

set LIB=C:\Program Files (x86)\Windows Kits\10\Include\10.0.19041.0\ucrt
set INCLUDE=C:\Program Files (x86)\Windows Kits\10\Include\10.0.19041.0\ucrt

before running python setup.py, also tried to run in the VS Studio Administrator: Windowds PowerShell and still the same issue.

And also when I am trying to run %VS140COMNTOOLS%vsvars32.batcommand prompt shows:

ERROR: Cannot determine the location of the VS Common Tools folder.

I had the same issue and I fixed it by :

1. install python-3.11.2-amd64.exe (to fix many prbl like err cl.exe code 2) and check if the problem gone if not go to the next steps :
2. download VISUAL COMMUNITY 2022 installer
3. run .exe and pick PYTHON DEVELOPMENT in the left side
4. in the right side: pick and download python native development tools option
5. pick and download python web option
6. start downloading and installations
7. run pip install setuptools
8. run pip --upgrade setuptools
9. run pip install -your package-
