kivy-ios: install grpc ==> FileNotFoundError: [Errno 2] No such file or directory: '/bin/false

I am trying to install grpcio for kivy-ios on macos, but I am receiving the error “FileNotFoundError: [Errno 2] No such file or directory: ‘/bin/false’”

false does not exist in the /bin directory, but in /usr/bin directory. I do not know how to make the command look at this directory instead (check the “running shell” line in the log below and you will see: _env: {‘CC’: ‘/bin/false’, ‘CXX’: ‘/bin/false’

I have tried many changes, but I am still getting similar errors.

Can you please assist me.

the command run is:

toolchain pip install grpcio

THANKS!!!

[mawaki]

@AndreMiras I restarted my computer, and it finally allowed me to modify the toolchain.py. This error has been fixed, but I am having another error so I will open another issue. Thanks for your time and the help @AndreMiras.

Thanks for assisting me @AndreMiras, It does not allow me to modify venv/lib/python3.8/site-packages/kivy_ios/toolchain.py.
