I tried installing animation nodes. Blender thought it installed it but it actually didn't (because it was the windows version and I was using Linux). I realized this when I ran into this problem. So I deleted that zip and downloaded the linux one. Now it shows up in the Add-ons folder when I select the .zip (as shown below)
but when I click the checkbox to enable it, it gives me this error message:
Thinking that Animation Nodes is already installed, even though the Windows version didn't show up in the Add-ons panel or anywhere on my hard drive. How can I get the proper version installed?
bpy.utils.script_paths("addons")
into the python console. This will return a list of known addon locations. In my case['/home/batfinger/src/BlenderGIT/kdev_build/bin/2.78/scripts/addons', '/home/batfinger/.config/blender/2.78/scripts/addons']
Remove addon from one of these locations. If the addon is in the blender contrib, as is animation nodes, I'd suggest removing the .config one. $\endgroup$ – batFINGER Jul 26 '17 at 9:48
