MacOS version of a-shell show error when installing rubicon-objc

I am developing scripts that are using rubicon-obj to access Apples PhotoKit on iOS and iPadOS. For faster development cycles I tried to install rubicon-obj i the MacOS version of a-shell (Testflightbuild 536). I encountered an error:
"ERROR: Could not install packages due to an OSError: [Errno 1] Operation not permitted: '/etc/apache2/mime.types'"

In a-shell on iPad and iPhone everything works as expected.

I googled this error in combination with sandboxed app development and found this very old link on StackOverflow:
https://stackoverflow.com/questions/34420174/app-sandboxing-python-wandering-out-of-the-sandbox
Not sure it is really related, but it sound so for me.

I have no idea how to work around this issue or wether it is possible to solve but would be very happy if it could be fixed.
Please tell me if I can help. This would make the really great app even more perfect for me.
