Hi, I have been playing around with python on Leopard today. Overall, I am very pleased, but I just ran into a problem that will affect a large number of users.
In Leopard, Apple includes a number of python packages in: ls /System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python CoreGraphics easy_install.pyc setuptools-0.6c7-py2.5.egg-info OpenSSL fetchmailconf.py site.py PyObjC fetchmailconf.pyc site.pyc PyObjC.pth fetchmailconf.pyo site.pyo PyRSS2Gen-1.0.0-py2.5.egg-info libsvn svn PyRSS2Gen.py macholib twisted PyRSS2Gen.pyc macholib-1.2.1.dev-py2.5.egg-info wx Twisted-2.4.0-py2.5.egg-info modulegraph wx-2.8-mac-unicode Twisted_Words-0.4.0-py2.5.egg-info modulegraph-0.7.2.dev-py2.5.egg-info wxPython Twisted_Xish-0.4.0-py2.5.egg-info numpy wxPython_common-2.8.4.0-py2.5.egg-info altgraph numpy-1.0.1-py2.5.egg-info wxaddons altgraph-0.6.8.dev-py2.5.egg-info pkg_resources.py wxaddons-2.8.4.0-py2.5.egg-info bdist_mpkg pkg_resources.pyc wxversion.py bdist_mpkg-0.4.3.dev-py2.5.egg-info py2app wxversion.pyc bonjour py2app-0.4.1.dev-py2.5.egg-info xattr bonjour_py-0.2-py2.5.egg-info pyOpenSSL-0.6-py2.5.egg-info xattr-0.5-py2.5.egg-info dateutil python_dateutil-1.2-py2.5.egg-info zope easy_install.py setuptools zope.interface-3.3.0-py2.5.egg-info At first I was very excited to see that Apple is including things like setuptools, numpy, twisted...... But then I saw that some of the versions are quite old. Naturally, I grabbed the latest numpy version from svn and did a python setup.py install. Everything built just fine, but when I did an import numpy, I got Apples version: >>> import numpy >>> print numpy.__file__ /System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/numpy/__init__.pyc After looking at sys.path, it became clear what the problem is: Running python setup.py install on Leopard causes packages to be installed in the usual: /Library/Python/2.5/site-packages But, Apple put this directory _after_ /System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python in sys.path. This, even if a user installs a newer version of one of these packages, the builtin python will always use Apple's older version. Obviously, I can set PYTHONPATH to get /Library/Python/2.5/site-packages earlier in the sys.path list, but this is going to bite many people. Is this a bug that I should report to Apple, or is there a better work around? Also, this information needs to be posted somewhere so we don't see this question a billion times on various lists over the lifetime of Leopard.
