py2app + pyqt: Differences between command-line and double-click
by Berg, Stuart Aug. 15, 2013

Aug. 15, 2013

Hi, I'm using py2app to packages my (cross-platform) PyQt app into a Mac OS X application bundle. (py2app is great, btw!) I was wondering if anyone could point me to some documentation that explains in detail how a python app bundle's launch process differs from launching the python app directly from the command-line. My app bundle seems to function exactly the same in most respects, but my main window doesn't activate unless I manually activate the application via command-tab. I give a few more details in this question on stack overflow: http://stackoverflow.com/questions/16574315/qt-mainwindow-does-not-appear-u… Any ideas, suggestions, or links would be appreciated. Thanks, Stuart

OSAscript from python doesn't trigger privileges prompt
by fsteele＠mindspring.com June 25, 2013

June 25, 2013

I'm writing a Python application that looks for a pkg file in a particular location, downloads it, and installs it. Using osascript -e and Python's subprocess.Popen(), I can embed: do shell script "sudo /usr/sbin/installer -pkg /path/to/file/filename.pkg -target /" with administrator privileges When run interactively, this works fine. When the script hits the above line, it prompts me to enter my admin privileges and successfully runs installer. When triggered by a launchd agent (in /Library/LaunchAgents/), the script runs and does everything except successfully install the package. Any ideas what I'm doing wrong? Thanks! Frank

Ronald, Did you mean this to go to the list? I've forwarded it on... Anyway, thanks for the notes -- I'll keep all this in mind when I build that app again. >> I've learned a few things from this. >> >> 1) this is odd: >> right near the top, I see: >> prescript.py >> imports: Image >> that's the prescript for the PIL recipe -- I"m not using PIL, it >> seems it's runnign nthe recipe, and using what the recipe imported -- >> not good. > > Are you sure about not using PIL (if even indirectly)?

possible interaction between python
by Boyd Collier June 25, 2013

June 25, 2013

Hello All, In late February, I thought I'd give python a try, so I took steps to run it on my Mac. Unfortunately, I didn't keep a good record of what those steps were, but the installation seemed to be successful, in that I was able to run a few simple python programs. However, I now suspect that installing python may have messed up something needed to work with my objective-c programs with Xcode. The symptom of a problem in Xcode is that when I set an Xcode project to use LLDB as the debugger (this is the default debugger), Xcode immediately crashes when the run button in the project window is hit. However, projects run properly when I change the debugger to be used to GDB. At least initially, there was no indication that this problem had anything to do with python. I filed an Xcode bug report with Apple and have been following the steps suggested by Apple engineers to try to track down the problem. This morning, they asked me to run the command /Applications/Xcode.app/Contents/Developer/usr/bin/lldb /bin/ls from the terminal, which I did. Here is the result: > Macintosh:~ bcollier$ /Applications/Xcode.app/Contents/Developer/usr/bin/lldb /bin/ls > dyld: Library not loaded: /System/Library/Frameworks/Python.framework/Versions/2.7/Python > Referenced from: /Applications/Xcode.app/Contents/Developer/usr/bin/../../../SharedFrameworks/LLDB.framework/LLDB > Reason: image not found > Trace/BPT trap: 5 My (perhaps erroneous) recollection is that I installed python 3.3, and I see that what is not being loaded is 2.7. I've sent this result to Apple, but perhaps those of you who have been working with python on the Mac and using Xcode might have experienced a similar problem and might be able to suggest what is going on. I'm running OSX 10.7.5 and Xcode 4.6 (but first had the problem with Xcode 4.2). Thanks very much, Boyd Collier Prof. of Biology, Emeritus San Diego State University

Dependency between pyobjc and py2app?
by Dinu Gherman June 4, 2013

June 4, 2013

Hi, after a longer break I've been looking into PyObjC again, installed a fresh framework-built Python followed by the pyobjc package as de- scribed here: http://pythonhosted.org/pyobjc/install.html Then, running a few samples from this page: http://pythonhosted.org/pyobjc/examples/index.html revealed that py2app was missing which I had to install seperately as Ronald kindly pointed out. So ok, this could clearly be better indicated on the installation page above, but what I really wonder is if pyobjc and py2app can be useful as stand-alone packages or if they are not so much tied to each other that there should be a dependency in pyobjc on py2app, installing the latter automatically with the former? Regards, Dinu
