Unable to install development environment on Mac from master or tags/2020.2.10

I am running MacOX 10.15.7 python 3.6.12

after installing with pip ie

pip install -e .

from the root directory. This did not work at first, I had to run

pip install pyobjc==6.2.2

6.2.2 is the version current when I last had this running (the current version (7.0.?) would not pip install due to compilation error)
After I install pyobjc==6.2.2 then

pip install -e . 

ran and reported that PsychoPy had been successfully installed

When I run

PsychoPy

or

python psychopy/app/psychpyApp.py

I get the following

Exception Type:        EXC_CRASH (SIGABRT)
Exception Codes:       0x0000000000000000, 0x0000000000000000

I am also unable to install Psychopy as part of my python distribution on Catalina, so I would also appreciate to have some input on this…best of luck!

I am not sure what you are trying to do, but you could make the changes in your installed standalone. That will get around the packaging problems we seem to be having and you will be able to do your experiments locally on your machine. Distributing it to other people will be difficult.
