[GRASS-user] Sqlite error when calling GRASS GIS outside of GRASS

[DAmico, Ellen]

Hi,

Thanks for the suggestions.  I do have the paths set up.  Like I said I can only set these through Spyder and not in my path variables directly because I do not have admin privileges to my work machine, I am not sure if this causing problems or not.



If you can give me an example of how you set up the GISRC that might be helpful because perhaps I don't have that set up properly.



I have run through the link you have sent several times already.  I was able to run all of the python example codes successfully, except the one for using pygrass.  I think would suggest that I don't have the path set up for the library set properly.

I also tried your suggestion about removing the path from the module name.  That gave me the exact same error so that is not the issue.



Here is how I have the other paths set up.

First of all, there are a series of variables you have to define before you can call a module without starting GRASS GIS explicitly. See [1] or use the exec parameter of the grass command.



Second, when using the functions in the grass scripting library (e.g. run_command), you should not provide a path, but just the module name, i.e.



g.run_command('g.proj', georef=geotiff, location = locationGeonet)
