Python 3. OS/X 10.6 Ipython
by John Riordan April 9, 2011

April 9, 2011

I am trying to get IPython running with Python 3.1 on OS/X 10.6.3. The install script for IPython configures it to run with Python 2.6. Is there a way around this?

2.7.1 build?
by Christopher Barker Dec. 14, 2010

Dec. 14, 2010

Hey folks (or should I say Ronald?), What's up with binary builds for 2.7.1? Python.or has recently released 2.7.1, but there are no mac binaries yet. This wouldn't be a big deal -- I'm patient, but unfortunately the way the python.org web site is set up, it's easy to find 2.7.1, but next to impossible to find 2.7.0 -- they appear to only put in links to the latest minor release. I say "next to impossible", because I haven't found it yet, and I've been poking around the web site for a few minutes. so, we really need either a set of 2.7.1 builds, or at least a link on the python.org site somewhere obvious for the 2.7.0 builds! -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chris.Barker(a)noaa.gov

OS X compatibility of Appscript
by Mark Johannessen Nov. 20, 2010

Nov. 20, 2010

I think I've tracked down this error to the use of a python Appscript call: The process has forked and you cannot use this CoreFoundation functionality safely. You MUST exec(). Break on __THE_PROCESS_HAS_FORKED_AND_YOU_CANNOT_USE_THIS_COREFOUNDATION_FUNCTIONALITY___YOU_MUST_EXEC__() to debug. This is on a machine that has: Python 2.6.6 (MacPorts installed) OS X 10.5.8 PPC Appscript 0.21.1 (easy_install-2.6) Django 1.2.3 (using easy_install) Other than pages using Appscript, everything works fine. Am I using the right Appscript? Mark J

How to add appscript module to a pyobjc project?
by Fur Yao Nov. 18, 2010

Nov. 18, 2010

I have some problem In my app , I want to use "appscript" . I use easy_install appscript , and it works well in my python script. But when I build a Mac app in xcode , an error appears. >>> from appscript import app , k ImportError: No module named appscript >>> Then I copy the appscript folder direct from "/Library/Python/2.6/site-packages/appscript-0.21.1-py2.6-macosx-10.6-universal/" to the app's Resources folder. and I also copy aem mactypes.py osax.py And it appears: "ImportError: Bad magic number in /Users/Kebot/git/Giraffa/build/Debug/Giraffa.app/Contents/Resources/appscript/__init__.pyc" Forgive my poor English. -- Blog: http://kebot.me/ More About Me: http://about.me/yaofur/

Searchable digest for this list?

Is there a searchable digest for this list? I'm looking to resolve the following error which seems to be tied to appscript: Break on __THE_PROCESS_HAS_FORKED_AND_YOU_CANNOT_USE_THIS_COREFOUNDATION_FUNCTIONALITY___YOU_MUST_EXEC__() to debug. Mark J

bdist_mpkg permissions bug
by Russell E. Owen Nov. 12, 2010

Nov. 12, 2010

bdist_mpkg 0.4.4 has a nasty habit of making data files unreadable by anyone except the file owner (the umask ends in 00). For example when using bdist_mkpg to make an installer for matplotlib for all files in mpl-data end up with this issue. There is a workaround: let bdist_mpkg run to completion, then delete the mpgk, fix the permissions in the build directory and run bdist_mpkg again. Any idea who (if anyone) maintains this package and what might have changed to cause this problem? Older versions of bdist_mpkg did not exhibit this problem, though I'm not sure exactly when it appeared, nor whether it is in bdist_mpkg itself or a package it relies on. -- Russell

Select application version
by Carles Pina i Estany Nov. 8, 2010

Nov. 8, 2010

Hello, I'm not an advanced Applescript user, but I usually have a problem: how can I choose the application version that I want my script to connect to? Let's say that I have Microsoft Office 2004, 2008 and 2011. How can I select the version in the tell statement? The final use case is using Python, I thought that appscript.app() could have some argument to specify it, but it seems that it doesn't have any. I also tried appscript.app("Disk:Applications:Microsoft Office 2011:Microsoft Word") without any luck ("Local applicatoin "Disk:Applications:..." not found) Thank you, -- Carles Pina i Estany http://pinux.info

Re: [Pythonmac-SIG] __import__('pkg_resources').declare_namespace(__name__)
by Erik van Blokland Nov. 6, 2010

Nov. 6, 2010

I've found something interesting. When using setuptools-0.6c11-py2.6.egg importing pkg_resources causes Carbon and PyObjCTools to be loaded. With setuptools-0.6c9-py2.6.egg this is not the case. This is relevant in situations where one doesn't want to import OSX API modules before daemonising a process. For instance, when starting a twisted server. I don't know about why the c11 version imports these modules. I'm glad I found a workaround. But the problem is bound to come back. So, any clues to what c11 does that c9 doesn't? Thanks! Erik

Amateur question about modules
by Pedro Gazzola Nov. 5, 2010

Nov. 5, 2010

"ImportError: No module named tkSnack" I tried to run one script on the Python Launcher and got this import error. So, how can I correctly import this module? And where should I put it, so Python can find it. Thanks for any help.

[Pythonmac-SIG] __import__('pkg_resources').declare_namespace(__name__)
by Erik van Blokland Nov. 5, 2010

Nov. 5, 2010

Hi, Once more looking at the problem that keeps on giving. In short: http://code.activestate.com/lists/pythonmac-sig/22224/ Hard crash flagged with: USING_FORK_WITHOUT_EXEC_IS_NOT_SUPPORTED_BY_FILE_MANAGER Background: A helpful person on the twisted.web list found that loading specific modules (pyobjc, Quartz) before a script was daemonized causes OSX 10.6 to crash. He fixed my test script by delaying OSX specific modules until after daemosing. The test script works locally. However, running the same test script on a mac mini server still has the same (or similarly flagged) crash. Both machines have the same python version, OSX version, pyobjc, twisted versions, 64bit, even user ID. Running it remotely via SSH or in a GUI yields the same results, (ssh into local machine, script works, ssh into remote machine, script doesn't work, screensharing into remote machine, script doesn't work) Problem: Another helpful person suggested there might be other modules that get loaded before daemonising. So I dumped sys.modules before and after daemonising, both local and remote, and compared. On the remote machine the MacOS and Carbon modules are loaded before daemonising, on the local machine they're not. (NB, I don't know if these imports are relevant to the Fork crash, but it seems prudent to find out). None of the modules called by my test script call Carbon directly but I found this line in a zope init, (a dependency of twisted) loads Carbon. The cryptic import: __import__('pkg_resources').declare_namespace(__name__) I don't know what this means. Which conditions on the remote machine would cause this line to load Carbon? #Test: import sys def printCarbonLoaded(when): print ("%s carbon is"%when), "Carbon" in sys.modules.keys() printCarbonLoaded("1") __import__('pkg_resources').declare_namespace(__name__) printCarbonLoaded("2") Results: local machine: 1 carbon is False 2 carbon is False remote machine: 1 carbon is False 2 carbon is True Many thanks, Erik
