For information, a reply from Jim Bosch about eups and virtualenv. It
seems that mixing this two software may be quite difficult ...

Commented by jbosch:
I think I agree with your statement about what eups' behavior should be,
but I'm afraid I'm not enough of a eups expert to be able to make that
change myself (or even understand all its ramifications). I'm somewhat
concerned about the idea of trying to use virtualenv with eups, though,
as I think they're likely to conflict in more ways than this. As I
understand it, both of them want to take control over your environment
and determine which versions of other packages will be used, and I'm
concerned that makes them fundamentally incompatible.
In reply to fjammes's question: Installing virtualenv with eups
Hello,
I need to install virtualenv with eups but i run in a tricky problem :
|[eups@clrlsst-dbmaster-vm eups]$ /usr/bin/python -S -c "import traceback"
[eups@clrlsst-dbmaster-vm eups]$ /opt/lsst/Linux64/python/virtualenv/bin/python -S -c "import traceback"
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named traceback
|
So, it seems virtualenv doesn't import all python standard library.
The problems is that after having installed virtualenv, eups use
opt/lsst/Linux64/python/virtualenv/bin/python and return next error
message :
|[eups@clrlsst-dbmaster-vm eups]$ eups
Traceback (most recent call last):
File "/opt/lsst/eups/bin/eups_impl.py", line 26, in <module>
import eups.cmd
File "/opt/lsst/eups/python/eups/__init__.py", line 1, in <module>
from exceptions import *
File "/opt/lsst/eups/python/eups/exceptions.py", line 5, in <module>
import sys, traceback
ImportError: No module named traceback
|
So, my build scripts, or setup/unsetup commands doesn't work anymore.
Is there a way to force eups to always use a fixed python version ?
Thanks,
Fabrice
