Dear Alexadris,
I am using GRASS GIS 7.8.5 and trying to install the add-on module.
Whenever I attempted to install the module, GRASS GIS issued the attached error message.
I used the module a few years ago, at that time there was no problem in installing it.
Would you please look at the error message and let me know any solution?
I will use the module to teach my lab for undergraduate students.
Thank you for your consideration in advance.
P.S. The GRASS GIS was installed via OSGeo4W.
Sincerely,
