[GRASS-user] grass-python scripting error

Mon May 25 00:23:40 EDT 2009

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):
  File "./python_grass03.py", line 13, in <module>
    options, flags = grass.parser()
  File "C:\OSGeo4W\apps\grass\grass-6.4.0RC4\etc\python\grass.py", line 208,
in parser
    os.execvp("g.parser", [name] + argv)
  File "c:\Python25\lib\os.py", line 354, in execvp
    _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.
