New submission from Karsten Petersen <ka...@kapet.de>: [Guido asked me to file this as an issue.]
On Mac OS X Apple has configured the system provided Python to also search this global site-packages directory: /Library/Python/<version>/site-packages/ This allows users to install their own system-wide packages there (and not have them to drop into /System/Library/Frameworks/Python....../). Unfortunately if you install Python from python.org (or pythonmac.org) it is not searching this path, it only searches the site-packages directory _within_ its own framework: /Library/Frameworks/Python...../ That directory is of course not searched by the Apple provided Python. This is an issue for addon package installers (think PIL or numpy): There is no single path that will be found by both the system provided Python and a Python installed from python.org. This makes most/all (?) of the pre-built packages on pythonmac.org unusable with the version of Python Apple ships although there is no version conflict or such - it simply installs stuff in the "wrong" directories. Many people who tried to install PIL for Django or App Engine stumbled into this. The system provided Python version was fine. But compiling PIL is hard. So they installed PIL from pythonmac.org. That couldn't be found by Python. Now some people manually copied stuff around, some created symlinks, some installed a second Python 2.5. (The lucky ones picked a Python download from python.org, the not so lucky ones installed the 2.5.0 release from pythonmac.org...) I've attached a diff of a stock Python 2.5.1 library against what I found on my Apple Mac OS X 10.5 (Leopard) system. I've dropped changes that are not related to the path. ---------- components: Library (Lib), Macintosh files: apple.diff keywords: patch messages: 79329 nosy: kapet severity: normal status: open title: system wide site-packages dir not used on Mac OS X type: behavior Added file: http://bugs.python.org/file12637/apple.diff _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue4865> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
