[gentoo-user] change python version for special program

[Kraus Philipp]

Hello,

I have installed Python 2.7 & 3.2.2 on my Gentoo box, but I would like to use Scons, which runs at the moment under Python < 3.
I have installed Scons with "python2.7 setup.py", but if I run "scons" on command line, it creates the message, that it runs not on Python 3,
so can I setup manually that scons should use the Python 2.7 interpreter?

Thanks

Phil

As root:

eselect python list

I'm surprised you had to take the setup.py install route. Is scons not
available in someone's overlay?

It's in portage:

$ equery list -p -o scons
 * Searching for scons ...
[-P-] [  ] dev-util/scons-2.0.1:0
[-P-] [ ~] dev-util/scons-2.0.1-r1:0
[-P-] [  ] dev-util/scons-2.1.0:0
[-P-] [  ] dev-util/scons-2.2.0:0

Latest version, stable even.

That's what I get for assuming. Power's out at home, so I couldn't
even run a quick 'eix'...

With this option I can setup the global Python version. Can I change only for one program ?

I'm testing different versions, because I would like to debug a scons toolkit.
So I haven't installed the portage Scons version, I have downloaded the tarball
and installed them within my home

Create a virtualenv would be a better solution. 

Google virtualenv

Thanks, I don't have read anything about it, it is my first time, but I think it is the best solution for my problem

Hi,

just editing the shebang to point to python 2.7 wouldn't solve your
problem ?

Cheers,
