Dear Grass friends,
I prepared a simple python3 script that runs correctly using Grass 7.8 on GNU/Linux.
I put the module in the script folder of /usr/lib/grass78. The parser is able to open the interface and the module runs.
Someone asked me to run the same script using Grass on Windows (the standalone version 7.8).
I put the script on the "C:\Program Files\GRASS GIS 7.8\scripts" folder.
When I run a the script, even only with the --help option (mySimpleGrassScript --help) from the Layer Manager Console, i get the error listed at the end of this e-mail.
May I kindly ask your help to understand what I have to check or to modify in order to run the code on window ?
thank you very much
Ivan
The error I get:
