extraVAELoader issue: No module named 'diffusers' #106

I downloaded the sana comfyui workflow just like it's shown on numerous youtube videos, but it just doesn't work.

I can't get this error to go away no matter what I do. I updated comfyui, added custom nodes, the sana custom nodes from github, I installed the diffusers package globally, I activated a venv and installed diffusers it in the venv, I created a new bat file to launch comfyui from the venv. Nothing works. How do i resolve this error?
