UNABLE TO INSTALL ON ALREADY DOWNLOADED AND COMPLETLY WORKING COMFYUI

[parthwagh9999]

I have completely working comfyui, which I use daily.
I have asked solution on ChatGPT, but nothing is working.

I am trying to install it manually, but nothing is working:
I tried "pip install -e .", but is giving me error.
I also tried to run through anaconda, but still same error.
Tried reinstalling numpy, also.

These are chatgpt instruciton I have followed:::

Please provide me solution.
Thank you.

I have Cuda installed. But I don't know is it compatible with the required version for this node.
