@bahman thanks. added to the docs.

I ran into this issue as well, setting up RoboFont on a new computer. I'm not sure exactly what caused it, because I think I tried to install the shell command previously, but got caught with something else. Just in case someone else comes across this, I solved it by: installing PyObjC with pip install -U pyobjc (I found out this was already installed) navigating to /usr/local/bin/ deleting /usr/local/bin/roboFont installing the shell command again

well spaces in a folder are never a good idea :)
