Visual Studio file can't be found from pip install command

Question

I'm trying to install 'lws' using pip, but when I run "pip install lws" I get an error, saying
lws.bycython.cpp(196): fatal error C1083: Cannot open include file: 'longintrepr.h': No such file or directory

"

lws.bycython.cpp(196): fatal error C1083: Cannot open include file: 'longintrepr.h': No such file or directory

"

The full output is listed below.

I uninstalled Visual Studio 2022 after uninstalling all of its workloads. After that I got the error "Microsoft Visual C++ 14.0 or greater is required"

After reinstalling Visual Studio 2022 and the I received the Visual Studio Build Tools I received the error again,

lws.bycython.cpp(196): fatal error C1083: Cannot open include file: 'longintrepr.h': No such file or directory

  error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2022\\BuildTools\\VC\\Tools\\MSVC\\14.39.33519\\bin\\HostX86\\x64\\cl.exe' failed with exit code 2
```I've looked on my computer and the file "cl.exe" exists right where the error says it should be.  
What more can be done? Perhaps something is messed up in the registry?

I have been able to install it. For future viewers having the same problem, I installed WSL (Linux console environment provided by Windows 11) and installed python3. I ran the command "pip install lws" and it ran fine.

The error when trying it in windows was that the file "longintrepr.h" was missing. I found that file in the wsl python folder and copied it to my windows folder and it works fine now.

Copied file from:

\wsl.localhost\Ubuntu\usr\include\python3.10\longintrepr.h

Copied file to:

C:\Windows.old\Users\username\AppData\Local\Programs\Python\Python311

Hope that helps some people in the future
