I'm trying to use grass.script and grass_session in a standalone python script on my MacOS device, but I always get error messages that tells me specific environment variables aren't set in the right way:
RuntimeError: Cannot find GRASS GIS start script: /Applications/GRASS-8.2.app/, set the right one using the GRASSBIN environm. variable
RuntimeError: GRASS GIS start script: /Applications/GRASS-8.2.app/Contents/MacOS/grass.sh --config path, return as GISBASE a directory (Rebuilding Addon HTML manual pages index...
Rebuilding Addon menu...
/Applications/GRASS-8.2.app/Contents/Resources) that do not exist.
I already tried a lot of different environment variable combinations without success:
export GRASSBIN="/Applications/GRASS-8.2.app/Contents/MacOS/Grass.sh"
export GRASSBIN="/Applications/GRASS-8.2.app/"
export GISBASE=/Applications/GRASS-8.2.app/Contents/Resources
If I'm running the desktop version of GRASS GIS and execute the env command in the shell, I'm getting the following ouput:
