Error during installation

[Saintpetr]

I did all the steps described in the installation (several times) and in this step:
python -m pip install -r requirements.txt
I get this error:

Building wheels for collected packages: hnswlib, gputil

I have Visual C++ Build tools installed in version 17.12.0, which corresponds to the requirement of 14.0 or greater.

Please advise how to solve this error

Same!

If you install it in a virtual environment (including the official portable package), you will be prompted that the python.h header file is missing, because the nano-graphrag library added by the author this time needs to be compiled and installed, and it requires a complete python development environment, including python.h header file (according to the version of python in your environment) and the “python311.lib” file in the libs directory (also according to the version of python in your environment), which can only be compiled and installed by compiling this library if these conditions are fulfilled. (depending on the version of python in your environment), and the “python311.lib” file in the libs directory (also depending on the version of python in your environment), which must be met in order for the library to be compiled and installed.

I do not install tools in a virtual environment, but directly in Win10.

When I repeatedly tried the installation using the Manager in ComfyUI (and not the "-hardest way"), I got a different error message, here is the statement:
