Installation failure on Windows while installing vllm-0.10.0

Hey!

Attempting to install vllm==0.10.0 on Windows using Miniconda3 + Python 3.12 results in a wheel build failure. The error occurs during the creation of quantization config JSON files, where the build system attempts to createpaths containing commas and brackets. Windows fails to create these paths, causing the install to abort.

This blocks local development for serving the model.

error: could not create 'build\bdist.win-amd64\wheel\.\vllm\model_executor\layers\quantization\utils\configs\N=1536,K=1536,device_name=AMD_Instinct_MI300X,dtype=fp8_w8a8,block_shape=[128,128].json': No such file or directory

It looks like vLLM is only supported by WSL when running on Windows?

This happens consistently when running:

python -m pip install -r requirements.txt

OS | Windows 11
Python | 3.12
vLLM Version | 0.10.0

Any assistance would be greatly appreciated

Thanks!

Start with requirements.txt and reproduce the python -m pip install -r requirements.txt failure on Windows 11 with Python 3.12. Inspect how the quantization config JSON paths are created, and verify the documented platform support; done means the Windows installation either completes successfully or the unsupported configuration is clearly established.
