How to set python version for org-babel

How to set python version for org-babel

[David Trem]

Hi,

 I'm currently learning org-babel with python.
I have several version of python installed on my Mac.
One from apple and two from macports.
I'd like to use python2.6 from macports.
I tried to set the python-python-command variable to python2.6
but the python 2.5 from apple is still used by org-babel.

I need some help to go forward.

Thanks in advance,

David

Hello,

Can you specify which version of Emacs you are using ?

I anticipate one of the aqua version: you need to set manually the  
path accessible to GUI apps in OS X: this is done by editing the file  
~/.MacOSX/environment.plist and adjust the path therein.

After you add the path to the macports executable directory (before "/ 
usr/bin" directory) the python command that is present there (if  
there is a python there, check with "which python" in a terminal)  
will be given priority.

HTH, and do not hesitate to ask for more details if needed,

Pierre

On my system I believe the variable is named `python-command', maybe try
the following...

(setq python-command "python2.6")

Thanks to Pierre and Eric help, I had all elements to
solve my issue. But before explaining my solution
let me give more detail on my setup:
MacOsX 10.5.8
Emacs 23.1 (from macports)

I had to add in my .emacs
(setq python-python-command
"/opt/local/Library/Frameworks/Python.framework/Versions/2.6/bin/python")

and add PYTHONPATH variable to the ~/.MacOSX/environment.plist
pointing to the corresponding python2.6 site-package folder.

I'm not sure I understand what is going on. This looks like
quite dirty fix but it works for now...

Thanks again,

David
