[GRASS-user] r.futures not working

[Helmut Kudrnovsky]

[keep always the mailing list in the loop that other community members are able to help too respectively benefit from the thread]

regarding OSGeo4W-winGRASS, unfortunately there was a change in the rbatch package recently which breaks adding R to %PATH%

*start OSGeo4W in advanced mode, type rbatch in the search window on the top left
* open the tree of "Command_Utilities" and "Libs" and choose version 149-4 instead of 149-5
* finish installation
* open OSGeo4W shell and type R
* then R should start in OSGeo4W shell

regarding Mac, others have to answer, no Mac available here.

kind regards
Helmut

Hi Helmut,

I got the latest versions of R, python and Grass installed. I get the same error message on Windows, mac and Manjaro. 
 
 
Do you know where the problem is?

Hi Helmut,
 
I've been using the OSGeo4W installer for everything, as it was suggested in the r.futures workshop.
 
I'm using Python 3.7, but I tried already different versions (2.7, 3.9) in the process of trying to fix the problem. 
I do not know whether it is bundled with grass though. How can I figure that out?
 
Thanks for your help!
 
Warm regards
 
Tom

which winGRASS version are you using? standalone winGRASS? OSGeo4W winGRASS?
QGIS bundled winGRASS?

>D:\Programme\apps\Python37\

which python are you using? is it the phyton bundled with winGRASS?
