Hello,

Recently, I attempted to install Compas-dev and Compas\_slicer.  
I did this, because I would like to work with the open-source slicer!!!  
There seems to be an issue, I don’t have access to the grasshopper components.  
I am not a software engineer, so rebuilding them from scratch is a bit daunting….

I can prove that Compas is maybe installed correctly; when I execute the code from the working with rhino section:

import compas  
print(compas.\__version_\_)

I get 2.15.

However, not only do I not have grasshopper components showing, when I recreated this just now, I get this error:

Whereas last night it displayed the mesh square just fine…. I am super interested in working with external python libraries with grasshopper…  
Seems like I’m just having some major errors installing things?

Not sure if I’m a complete dummy or if it’s because I updated my rhino version to 8.25.25328.11001, 2025-11-24  
I’m on windows 11 BTW  
The rhino updates do seem to change things pretty drastically.
