[GRASS-user] Running a python script using GRASS GIS on a Mac

[Shaffiq Somani]

Dear Moritz,

Thank you for your response since its greatly appreciated.  Sorry, I just saw your message since it went into the spam folder.  I have a couple of questions for you if you have a moment free.  I looked at the Linux environmental variables which is export GRASS_BIN=/usr/bin/grass78, ​but changed it to GRASSBASE and opened up the unix file as shown in the screenshot below.  I still get the following errors. Is there anything else that I am missing or should I be doing this another way.  Thanks.

Kind Regards,

Shaffiq

As you can see here, GRASSBIN points to the actual 'binary' file that contains the GRASS GIS launch script (grass78). In your example it seems to me that you only point to the directory that contains it, not the actual file. Try adding the name of the file to your path.
