I added the “inset extrude” addon into Blender. It shows up on the User-Preferences>Addons, but it won’t let me check the box to enable the addon. I tried typing in the code into the Python console and got this error:
Traceback (most recent call last):
File "C:\Users\Isaiah\AppData\Roaming\Blender Foundation\Blender\2.57\scripts\modules\addon_utils.py", line 219, in enable
mod.register()
File "C:\Users\Isaiah\AppData\Roaming\Blender Foundation\Blender\2.57\scripts\addons\mesh_inset_extrude.py", line 623, in register
km = wm.keyconfigs.addon.keymaps.new(name='3D View', space_type='VIEW_3D')
AttributeError: 'bpy_prop_collection' object has no attribute 'addon'
How do I fix this? I’m running Blender 2.7.
