Hi again,


sorry for posting again, but somehow I can't get it work to
run GRASS GIS using my local Python 2.7 installation.

So what I tried now were three different settings in the env.bat

1)
rem Path to the python directory
set PYTHONHOME=%GISBASE%\Python25
rem if "x%GRASS_PYTHON%" == "x" set GRASS_PYTHON=python
set GRASS_PYTHON=C:\Program Files (x86)\Python27\pythonw.exe

in this case: GRASS is starting using the Python25

2)
rem Path to the python directory
rem set PYTHONHOME=%GISBASE%\Python25
rem if "x%GRASS_PYTHON%" == "x" set GRASS_PYTHON=python
set GRASS_PYTHON=C:\Program Files (x86)\Python27\pythonw.exe

in this case: Nothing is started!

3)
rem Path to the python directory
rem set PYTHONHOME=%GISBASE%\Python25
rem if "x%GRASS_PYTHON%" == "x" set GRASS_PYTHON=python
set C:\Program Files (x86)\Python27
set GRASS_PYTHON=C:\Program Files (x86)\Python27\pythonw.exe

in this case: Nothing is started!


Just to inform you why I need that: I wrote a .py script (including g.parser elements) which I want to call inside GRASS with "file.py" (like any other modules e.g. r.fuzzy etc.) The script is working (tested on my Mac using GRASS in combination with Python 2.7)! The script calls scipy which can only be used in combination with Python 2.6 or newer (so far as I remember).


So hopefully this issue can be solved as soon as possible as I want to use the script also on my windows-office computer!!

Thank you
Johannes
