Grasshopper: No module named compas_fab

Hi, why this error appears?

Runtime error (ImportException): No module named compas_fab

Hi @seghier,
This command that you are using will install a compas package in Rhino, but only if you have already installed it on your environment beforehand. I believe what happens is that you’ve skip that step, so, make sure compas_fab is installed in your environment first (i.e. conda install compas_fab) and then you can try the rhino step.

However the Rhino step can be simpler, if you just type: python -m compas_rhino.install, it will install in Rhino all the existing compas extensions in your system, so you don’t have to explicitly do the -p compas_fab step at all.

I hope this helps!
