Impossible to install the node even with following instructions for Comfyui portable => solutions

[P1LeFR]

Install is not working:
pip install -r requirements.txt

Lead to crash :
Installing build dependencies ... done
Getting requirements to build wheel ... error
error: subprocess-exited-with-error

× Getting requirements to build wheel did not run successfully.
│ exit code: 1

This things is not focusing on the embedded python but look for the local python
So the line code shall refer to this therefore pip install -r requirements.txt is not correct for ComfyUI portable !

pip install --target=C:\Path\To\PythonEmbedded\Lib\site-packages -r requirements.txt

And it works ! Attention Python embedded do not have PIP ! This is why you need to use your system Python but to install the requirement in Python-embedded....

Hope it helps others,
Personally I'm feed-up with Python, and all it's versions, not compatible, the different environments vev, embedded, Python is a mess !

BUT this solve nothing still stuck with the wheel building !

After checking more this is a xformer issue ! Honestly I have never ever succeed to built a xformer wheel even following all instructions ! Solution download a wheel and install it directly in the embedded
