Does anyone know how to undo the changes to paths and permissions wrought by upgrading to El Capitan. Specifically, it appears that OS X is now using the system python instead of my Canopy installation.
These look ok:
Michaels-Mac-mini:~ mellis$ which python
/Users/mellis/Library/Enthought/Canopy_64bit/User/bin/python
Michaels-Mac-mini:~ mellis$ which ipython
/Users/mellis/bin/ipython
But trying to launch ipython fails:
Michaels-Mac-mini:~ mellis$ ipython
Traceback (most recent call last):
File "/Users/mellis/bin/ipython", line 5, in <module>
from pkg_resources import load_entry_point

pkg_resources.DistributionNotFound: ipython==0.11
A complete update of my installed Canopy packages including ipython seems to have fixed the problem.
