I downloaded Sverchok from Github - but when I try to enable it I am getting the following error:

[![Sverchok Installation Error][1]][1]

I am using Blender 2.80 Portable on Win 10 64bit.
I have no problem installing any other add-ons or Installing the older version of Sverchok on Blender 2.79b Portable.

Could anyone please help?
