how to get a particular git branch of sympy installed?

[Comer Duncan]

Hi,

I have a few branches of sympy. Among them is Stefan Krastanov's branch. I want to install (sudo python2.7 setup.py install)  it so that when I run ipython notebook --profile=sympy from anywhere it will use Stefan's.  So far I have tried checkout of his branch and find that his stuff is indeed there. I have also tried the 'sudo python2.7 setup.py install' but it does not provide what I want, branch-wise.  I have downloaded ipython and built it using python2.7 (which comes from macports).  The path to macports bin directory is first in my PATH (am running bash).  What do I need to do to get the functionality with the desired sympy from Stefan's branch?

Thanks for your help and advice.

That's weird --- does it mean that some other version (branch) of
SymPy is picked up instead?

I personally use Ubuntu, but the principle should be the same in Mac.
How did you
install ipython? Using "sudo python2.7 setup.py install"? If so, then
you should do
the same for SymPy. Maybe Aaron or others can comment.

P.S. I personally just use virtualenv, or install things into ~/usr using:

python setup.py install --prefix=$HOME/usr

and put "$HOME/usr/lib/python2.7/site-packages/" into my PYTHONPATH.
I never use "sudo" for installing things.

You can also try setupegg.py develop, which will setup some symbolic
links to make the globally installed sympy always point to the git
version. Then, whatever branch you checkout with git will
automatically become the globally installed version.

Regarding your other way (and actually this way too), make sure that
the command "python2.7" points to the macports Python (run "which
python2.7"). If you just use ./setup.py instead of python setup.py,
it will use the default Python (the first in your path). You can also
try /full/path/to/macports/python2.7 setup.py (probably
/opt/bin/python2.7).

I am unsure how setup.py works, however it may need to be updated with
the knowledge about my new module (as it is still WIP I have not done
that yet).

I personally just add my git folder to the PATH, so I never install it.

I did this and it seems to work fine.  Thanks.
