Hi everyone, I am a newbie in the Mac world, having bought my first Mac Mini a couple of days ago. I promptly went on to find out about Python programming there.
I installed Python 2.5 from python.org, so I have it besides 2.3. I also installed xcode 2.4. That is on OS X 10.4.8. Then I tried to follow "Using PyObjC for Developing Cocoa Applications with Python". Here is where small problems crop up. I would like to know the right solution about (some of) these problems. - Using xcode I followed the tutorial. I wasn't able to build. I get build failed with No module named py2app. I understand this comes with PyObjC so I tried to install that again. The installer for PyObjC 1.3.7 from http://prdownloads.sourceforge.net/pyobjc/pyobjc-1.3.7-py2.3-macosx10.4.zip?download gives me an error on import along the lines of unable to import due to "mach-o, but wrong architecture". I tried PyObjC 1.4 from source but it wasn't able to install due to a permission error. I didn't try to investigate that, especially as there is no binary for python 2.3 so I figured that something was amiss. Anyway, I tried to use Python 2.5. - To use Python 2.5 I installed PyObjC 1.4. The installation went smoothly. I had to modify setup.py to use /usr/local/bin/python following a hint somewhere the internet. Now "Build and Go" wasn't working (why?). Following another hint I mad a custom executable like "/usr/bin/env PyAverager.app/Contents/MacOS/PyAverager". This is now working. - The next problem is in the code itself. When trying to run the application PyAverager I get an error: PyAverager[3377] Unknown class `Averager' in nib file, using `NSObject' instead ... NSUnknownKeyException - [<NSObject 0x1427590> valueForUndefinedKey:]: this class is not key value coding-compliant for the key numbersInput So the nib (whatever that is) cannot find the class Averager. By going to the source of PyAverager I noticed that the Averager module is imported indirectly, as in: for pythonModule in info[u'Modules']: __import__(pythonModule) If I do "import Averager" or "__import__('Averager')" after these lines the application runs successfully. So I guess that info[u'Modules'] doesn't contain 'Averager'. So the important questions for me now are: - Is there anyway to automate the change of setup.py to use /usr/local/bin/python at each new project, rather than doing it manually? - Shouldn't "Build and Go" be working automatically? Or is there anyway to automate the creation of the custom executable for each new python project? - Why doesn't Averager in the example get imported automatically? Probably I did something wrong here, but I don't know what. These are my problems with Python 2.5. I guess I am not going to use Python 2.3 anyway, so it would be nice but not essential to know about the solution to my problems with it. Sorry for the long e-mail, but I figured that some of my problems might be known issues and/or bugs as well, so I better document these for others.
