Help with Installing Ladybug on Mac: Runtime error: No module named fcntl

Hi all, I’m trying to install ladybug on Mac, and I’m following the steps here: 1.2 Mac Installation Steps · ladybug-tools/lbt-grasshopper Wiki · GitHub

I’ve done step 1, and am trying to run the installer component in step 2, but I’m given a message saying “Runtime error (ImportException): No module named fcntl:”
Attached a screenshot below.
