I've upgraded to Catalina. It's been fine overall, but I just discovered today that fonttools is not working when I call it from a script. I can see it in the Python directory, and ttx still works from the command line. But if I try to run a script that calls fonttools, it says it's not defined. It seems that Python doesn't know about it anymore, and I'm not sure how to fix it.
Has anyone run into this, and if so how to fix it?
