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?

Simple PyObjC question: real or vapor?
by Temescal April 7, 2011

April 7, 2011

3 April 2011 My goal: Using my MacBook (intel 64 bit dual core), OSX 10.6.7, standard System python frameworks (2.6,2.5,2.3), a standard python install of 2.7 (32 bit) in a Library framework, Xcode 3.2.5, I would like to write some GUI based python programs for the Mac. My problem: 1) The Apple developer article "Using PyObjC for Developing Cocoa Applications with Python" is hopelessly outdated. PyObjC and py2app are not under the Developer folder but are under the System/Library/Frameworks/.../Extras/lib/python folder. Xcode new project has no option for selecting a PyObjC application, etc. 2) The PyObjC website ambiguously states "The stable release front is rather hazy at the moment, I'm sorry for that and intend to fix that in the near feature." The indications are, this was composed some time ago, as 2.3 appears to be the current package. The web site advises using easy_install, but the web has widely conflicting opinions on easy_install's value, and moreover the recommended command "$ easy_install pyobjc=2.2b1" fails. 3) I've used easy_install successfully exactly once to install lxml. I've shunned MacPorts and Fink because of the various web reports about their frailty, and also because using them seems to be incomprehensibly complex. I tried a variation on the PyObjC command: "$easy_install pyobjc" which runs, giving a plethora of errors, and installs various eggs in /Library/Python/2.6/site-packages, this despite "$which python" offers up python 2.7 as the default python. Moreover, as reported in another thread, _ScreenSaver fails to install. _2to3 is not recognized as a distribution option, suggesting that perhaps python 3 needs to be installed, but logically, if that were the case, it should be so reported by easy_install. Or, perhaps it can't find 2to3 which is in the standard Mac python distribution. Using "$easy_install py2app" works except for failing to install macholib, which is apparently crucial to running /usr/local/bin/py2applet, which it also installs. 4) Xcode 4, which I just learned about, seems to not support python at all, according to threads here. 5) Contributions to the various threads in this forum seem to be divided among those who, like me, are completely confused and frustrated, and those who seem to have working useful systems up and running and don't see any issues at all. My request: So in summary, in very simple terms, can anyone tell me how to accomplish my goal or tell me why my goal is unachievable with my existing tools, and what if anything can be done to correct the situation? I've probably put 40 hours of time into web searches and trying various things. It can't be this hard, and if it really is this hard, I just won't be writing GUI apps for the Mac, because I really like python, more than any other language I've used. I like python because it is clear, it works, it is well documented, and it is complete. Thus far, PyObjC is none of these. -- View this message in context: http://old.nabble.com/Simple-PyObjC-question%3A-real-or-vapor--tp31311493p3… Sent from the Python - pythonmac-sig mailing list archive at Nabble.com.

py2app improperly using system framework
by Nat Echols April 7, 2011

April 7, 2011

I'm using py2app from the latest SVN, along with an installation of Python 2.7 in a non-standard location. I don't get any error messages during running either py2applet or 'setup.py py2app', but at some point during app building, it starts copying over parts of the system's Python (2.6!) installation. Here is where it starts to fall apart: copying /net/clover/scratch1/python/bin/python -> /private/var/tmp/mac_app-dev-720/dist/PHENIX-dev-720.app/Contents/MacOS linking /private/var/tmp/mac_app-dev-720/dist/PHENIX-dev-720.app/Contents/Frameworks/python.framework/Python -> Versions/Current/Python linking /private/var/tmp/mac_app-dev-720/dist/PHENIX-dev-720.app/Contents/Frameworks/python.framework/Resources -> Versions/Current/Resources copying /Library/Frameworks/python.framework/Versions/2.6/bin/2to3 -> /private/var/tmp/mac_app-dev-720/dist/PHENIX-dev-720.app/Contents/Frameworks/python.framework/Versions/2.6/bin and then it proceeds to copy over most of the modules from 2.6. The resulting app is unusable, because it has the Python 2.7 binary which expects the modules in a 'python2.7' folder, but it's actually 'python2.6'. I've tried reinstalling everything multiple times and nothing I have tried works. This was working fine on 10.4 with py2app 0.5.2, but I had to upgrade py2app for it to even run on Snow Leopard. What am I missing here? thanks, Nat

Problem with py2app 0.6

I used easy_install to install py2app 0.6 and tried it out on one of several applications I distribute.
