python - GRASS parser() error -

i'm trying use grass on python 2.7, i'm having problems @ setting script on idle, i'm getting error @ parser() function:

here script:

import os import sys  gisbase = os.environ['gisbase'] = 'c:\program files (x86)\grass gis 7.0.1rc1' gisrc = 'c:\grassdata' gisdbase = 'c:\grassdata' location = 'newlocation' mapset = 'tc' ld_library_path = 'c:\program files (x86)\grass gis 7.0.1rc1\lib' path = 'c:\program files (x86)\grass gis 7.0.1rc1\etc';'c:\program files (x86)\grass gis 7.0.1rc1\etc\python';'c:\program files (x86)\grass gis 7.0.1rc1\lib';'c:\program files (x86)\grass gis 7.0.1rc1\bin';'c:\python27';'c:\program files (x86)\grass gis 7.0.1rc1\python27';'c:\program files (x86)\grass gis 7.0.1rc1\msys' pythonlib = 'c:\python27' pythonpath = 'c:\program files (x86)\grass gis 7.0.1rc1\etc\python'   sys.path.append(os.path.join(os.environ['gisbase'], 'etc', 'python'))  import grass.script grass  grass.parser() #i'm stucking here 

i'm getting error inside subprocess.py :

p = subprocess.popen([prog, '-n'] + argv, stdout=subprocess.pipe)

the full error:

traceback (most recent call last):   file "c:\users\ciro\desktop\teste_grass.py", line 19, in <module>     grass.parser()   file "c:\program files (x86)\grass gis 7.0.1rc1\etc\python\grass\script\core.py", line 680, in parser     p = subprocess.popen([prog, '-n'] + argv, stdout=subprocess.pipe)   file "c:\python27\arcgis10.1\lib\subprocess.py", line 679, in __init__     errread, errwrite)   file "c:\python27\arcgis10.1\lib\subprocess.py", line 893, in _execute_child     startupinfo) windowserror: [error 2] system cannot find file specified 

what missing?

based on grass source, trying run g.parser.exe unable find it. need set path environment variable correctly fix this.

you seem trying set system environment variables in bulk of code 1 in bash or batch scripts, if i'm not mistaken. setting , modifying python variables, tough. if want set environment variables other subprocesses (such grass) can see them, need modify os.environ variable, e.g.

os.environ['pythonlib'] = ... 

instead of

pythonlib = ... 

coming problem path environment variable, updating sys.path.append(...) , setting right locations in path = ... line above. latter not have effect due reason mentioned above. should need add sys.path.append(path) on top of rid of error seeing.
