Dear all,
I am trying to play with grass & python, and I am trying to
reproduce the first example available at
http://grass.osgeo.org/wiki/GRASS_and_Python
with the following adaptation:
#!/usr/bin/env python
import sys
import grass
def main():
drape_map = options[‘MQ_simulation_050001_p023_h007’]
relief_map = options[‘MQ_simulation_050010_p010_h013’]
brighten = options[‘brighten’]
ret = grass.run_command(“d.his”, h_map = drapemap, i_map = relief_map, brighten = brighten)
return 0
if name == “main”:
options, flags = grass.parser()
sys.exit(main())
To try this I started MSYS, started GRASS with -gui option,
and then typed the name of the script (python_grass03.py): The error looks like:
----…
GRASS 6.4.0RC4 (SDB_PL_teste):/c/Data/Paisagens_Simuladas/teste_python > python_grass03.py
Traceback (most recent call last):

os.execvp(“g.parser”, [name] + argv)

_execvpe(file, args)
File “c:\Python25\lib\os.py”, line 390, in _execvpe
func(fullname, *argrest)
OSError: [Errno 2] No such file or directory

The environment of my grass session looks like

Any hint are welcome.
