v.rast.stats: running generates "Unable to fetch interface description for command" error

[neteler]

Recent winGRASS 7 standalone installer - running v.rast.stats generates this error:

You run it from menu? (It is always better to include the information where you run the command from.) Is the version recent enough? Are there any other python scripts not running?

[neteler]

Replying to annakrat:

You run it from menu?

Yes (it was not my own machine but from a course participant)

Is the version recent enough?

Two days old.

Are there any other python scripts not running?

Other look fine. It is the v.rast.stats script which gave problems on various machines. From the error I don't know what to look for or check on the user's machine.

perhaps g.parser is looking for "v.rast.stats" but only "v.rast.stats.py" exists in the %PATH%, and it is missing the ".py" extension association? (that only works in the DOSbox window, not the MSys one AFAIK, and GRASS7 doesn't have the .bat file wrappers in bin/)

what does "set" say at the GRASS cmd.exe prompt? is ";.PY" known?

do other python scripts like r3.in.xyz work there?

Tested, seems to be fixed by relatively recent changes in calling Python scripts.
