I published a couple of improvements to py2app
by Virgil Dupras Aug. 22, 2010

Aug. 22, 2010

Hi all, I've been working on a few improvements for py2app. Since Ronald said he'd bring the repository to mercurial soon, I was waiting, but managing those patches became too much work so I converted py2app's SVN repo into a mercurial one and committed my improvements. These improvements are: Better py3k support: The "plugin" feature of py2app didn't work at all under py3k, so I went ahead and did it (thanks to a couple of helpful tips from Ronald). I also removed dependency on the Carbon module for the "--alias" option (the Carbon module is not available in py3k). Sphinx documentation: I converted the old docs to Sphinx. Option to use the built-in modulefinder instead of modulegraph: I was getting tired of having to write workaround imports to modulegraph (which doesn't like relative imports very well, even the latest version) and I didn't want to dig in modulegraph itself, so as an experiment, I added a "--use-modulefinder" option to py2app. I haven't tested it much, but so far, I'm able to build one of my apps *without* the workarounds I had for modulegraph, so it my case, it works better. So if you're interested in any of these improvements, the repo is at http://bitbucket.org/hsoft/py2app . All of these improvements are applied to the default branch, but still, each of them as its own branch, so you can pick which you want and apply them to py2app's trunk. -- Virgil Dupras

py2app and related packages on bitbucket
by Ronald Oussoren Aug. 22, 2010

Aug. 22, 2010

Hi, I've converted the repositories for py2app and related packages to mercurial and posted them on bitbucket. The new home pages are: py2app: http://bitbucket.org/ronaldoussoren/py2app macholib: http://bitbucket.org/ronaldoussoren/macholib modulegraph: http://bitbucket.org/ronaldoussoren/modulegraph altgraph: http://bitbucket.org/ronaldoussoren/altgraph I have disabled the wiki for now, but did enable the issue tracker. The pyobjc repository will also be converted to mercurial, but that's a more complicated process due to the more complicated history in that repository. Ronald

[py2app] No module named os
by Chris Weisiger Aug. 20, 2010

Aug. 20, 2010

I'm trying to use py2app to generate a standalone executable of a program I've made (major dependencies: wx, OpenGL, numpy/scipy). I've done this successfully several months ago, as evidenced by horribly out-of-date versions of the program that my users are still using because I can't get a newer version to work on their systems! I remember getting the thing working to be a bit of a chore, but unfortunately I didn't take notes on what all I did. Presumably the apps generated by py2app should not be dependent on changes that my users have made to their own systems. Doing "python setup.py py2app" apparently works, generating dist/editor.app which runs fine on my own computer. However, when run on a computer that is not my computer, I get the error "no module named os" and the program exits. Specifically, here's the complete error log from Console.app: 8/20/10 2:26:59 PM [0x0-0x1ad1ad].org.pythonmac.unspecified.editor[12219] 'import site' failed; use -v for traceback 8/20/10 2:26:59 PM [0x0-0x1ad1ad].org.pythonmac.unspecified.editor[12219] Traceback (most recent call last): 8/20/10 2:26:59 PM [0x0-0x1ad1ad].org.pythonmac.unspecified.editor[12219] File "/Volumes/KINGSTON/editor.app/Contents/Resources/__boot__.py", line 4, in <module> 8/20/10 2:26:59 PM [0x0-0x1ad1ad].org.pythonmac.unspecified.editor[12219] _chdir_resource() 8/20/10 2:26:59 PM [0x0-0x1ad1ad].org.pythonmac.unspecified.editor[12219] File "/Volumes/KINGSTON/editor.app/Contents/Resources/__boot__.py", line 2, in _chdir_resource 8/20/10 2:26:59 PM [0x0-0x1ad1ad].org.pythonmac.unspecified.editor[12219] import os 8/20/10 2:26:59 PM [0x0-0x1ad1ad].org.pythonmac.unspecified.editor[12219] ImportError: No module named os 8/20/10 2:26:59 PM editor[12219] editor Error (Incidentally, this used to complain about being unable to import traceback, until I turned off argv emulation) Some Googling suggested that I try unsetting environment variables at the start of my script as they might be interfering. So I added this to the top of my script: import os for key in ['PYTHONPATH', 'PYTHONHOME', 'PYTHONEXECUTABLE']: if key in os.environ: del os.environ[key] No dice. I tried manually inserting that same code into the top of __boot__.py; the only difference then is that it crashes at that "import os" invocation instead of the normal one. I thought maybe that I was using the wrong version of Python -- I know there's some annoying weirdness with py2app refusing to use the standard Python install. I have /usr/bin/python2.5, /usr/local/bin/python2.5 (the official install?), and /opt/local/bin/python2.5. The first one generates apps successfully, the second barfs because it can't find main-i386 even when I symlink main-fat3 to it, and the last doesn't have setuptools and therefore is presumably not the one I've used in the past. I haven't changed dependencies for the app itself since I last made a working app, and I know that it wasn't a Python 2.6 app. My setup.py script is as follows: from setuptools import setup APP = ['editor.py'] DATA_FILES = ['Priithon'] OPTIONS = {} setup( app=APP, data_files=DATA_FILES, options={'py2app': OPTIONS}, setup_requires=['py2app'], ) Any advice? Suggestions? I've run out of ideas myself. -Chris

Python 2.7 OSX install issues: site-packages and 32/64-bit
by Andrew Jaffe Aug. 18, 2010

Aug. 18, 2010

Hi all, I've been trying to move to Python 2.7 on Max OSX 10.6.4, and a few issues have arisen. The first is a changed location of site-packages and its relation to directories for setuptools/easyinstall. In recent versions <=2.6, the default site-packages was ~/Library/Python/2.6/site-packages but in 2.7, it seems to have moved to ~/Library/Python/2.7/lib/python/site-packages/ This mostly bit me when attempting to use setuptools, which [still] advises the following line in ~/.pydistutils.cfg install_lib = ~/Library/Python/$py_version_short/site-packages Is the new location canonical from now on? Should we permanently switch to that? The other issue seems to have to do with 32- vs 64-bit libraries, especially in my attempts to install matplotlib. This has bit me with wxPython, along with the libpng, zlib, and freetype dependencies (which have previously been grabbed from fink but which are 32 bit). Are there any magical hints for getting this to work (or binary installers which include all of these)? Yours, Andrew

Python 2.6/3.1 on Mac - default arch is i386?
by Sridhar Ratnakumar Aug. 16, 2010

Aug. 16, 2010

When Python 2.6 is built with --universal-archs=intel, the default Python binary is symlinked to the 32-bit binary: lrwxr-xr-x 1 root admin 12 10 Aug 15:31 python -> python2.6-32 Python 2.7, however, is 64-bit by default. Is there a particular reason why this behaviour is different for 2.6 (and 3.1)? -srid

That means the target application unexpectedly terminated (i.e. crashed) while your script was waiting for a reply. I would suggest filing a bug report on QuickTime Player <http://bugreport.apple.com>, ideally including an AppleScript that reproduces the problem.

ANN: py2app 0.5
by Ronald Oussoren Aug. 4, 2010

Aug. 4, 2010

Hi, I've just uploaded py2app 0.5 and new versions of altgraph, modulegraph and macholib. I hope this solves most issues with py2app. "easy_install-X.Y -U py2app" should install the software for you (where X.Y is your favorite version of Python) There is one new feature in this release: experimental support for python 3. This basicly means that I managed to build a single application as a standalone application bundle, without much testing. Alias builds and plugin bundles almost certainly don't work (the first because alias builds use the Carbon module which isn't available in python 3, the latter because I had to rewrite the C code in the application bundles and probably have to do the same for plugin bundles).

Appscript unpredictable error
by Sean DiZazzo Aug. 3, 2010

Aug. 3, 2010

Hi, I'm using appscript to do some work in Quicktime, and it keeps erroring out somewhat unpredictably. I am opening and closing lots of documents in quick succession when it happens. It doesn't happen every time, but about 70%-80% of the time. When it errors, it always errors trying to make a new document. ie. "qt.make(new=k.document)" Quicktime will quit unexpectedly, and after about 30 seconds I get: OSERROR: -609 MESSAGE: Connection is invalid. COMMAND: app(u'/Applications/QuickTime Player.app').make(new=k.document) I have also gotten error #1708:"the AppleEvent was not handled by any handler", but I can't seem to recreate the error. I tried putting in a time.sleep(1), before making the new document, but it didn't seem to help. Any ideas? ~Sean

py2app error
by Nathan Lemoine Aug. 3, 2010

Aug. 3, 2010

Hey everyone, I've been trying to bundle my script into a standalone Mac application using the most updated version of py2app and Python 2.5 on OSX 10.5.8. I'm getting error messages during the compile procedure and I haven't come across a way to fix it. So I can run the py2applet and generate the setup.py file easily. Here's the output when I attempt python setup.py py2app: Traceback (most recent call last): File "/Library/Python/2.5/site-packages/py2app-0.5-py2.5.egg/py2app/ build_app.py", line 604, in _run self.run_normal() File "/Library/Python/2.5/site-packages/py2app-0.5-py2.5.egg/py2app/ build_app.py", line 675, in run_normal self.create_binaries(py_files, pkgdirs, extensions, loader_files) File "/Library/Python/2.5/site-packages/py2app-0.5-py2.5.egg/py2app/ build_app.py", line 739, in create_binaries dry_run=self.dry_run) File "/Library/Python/2.5/site-packages/py2app-0.5-py2.5.egg/py2app/ util.py", line 376, in byte_compile if force or newer(mod.filename, cfile): File "/Library/Python/2.5/site-packages/py2app-0.5-py2.5.egg/py2app/ util.py", line 172, in newer msource = get_mtime(source) File "/Library/Python/2.5/site-packages/py2app-0.5-py2.5.egg/py2app/ util.py", line 164, in get_mtime info = zf.getinfo(rest) File "/System/Library/Frameworks/Python.framework/Versions/2.5/lib/ python2.5/zipfile.py", line 462, in getinfo return self.NameToInfo[name] KeyError: 'pyglet/__init__.pyc' > /System/Library/Frameworks/Python.framework/Versions/2.5/lib/ python2.5/zipfile.py(462)getinfo() -> return self.NameToInfo[name] So the KeyError would tell me that py2app does not have pyglet in its dictionary, so that it doesn't know where to search to find pyglet, correct? When I go into Python and find the path for the pyglet module (pyglet.__path__), I receive ['/Library/Python/2.5/site-packages/ pyglet-1.1.4-py2.5.egg/pyglet']. Do I have to tell py2app specifically where to find the pyglet module? If so, how do I do that. Also, whenever I run py2app in alias mode, I get a completely different error: sudo python py2app setup.py -A (sudo is run because I get a permission denied error if I don't use it( Traceback (most recent call last): File "/Library/Python/2.5/site-packages/py2app-0.5-py2.5.egg/py2app/ build_app.py", line 602, in _run self.run_alias() File "/Library/Python/2.5/site-packages/py2app-0.5-py2.5.egg/py2app/ build_app.py", line 548, in run_alias dst = self.build_alias_executable(target, target.script) File "/Library/Python/2.5/site-packages/py2app-0.5-py2.5.egg/py2app/ build_app.py", line 1145, in build_alias_executable appdir, resdir, plist = self.create_bundle(target, script) File "/Library/Python/2.5/site-packages/py2app-0.5-py2.5.egg/py2app/ build_app.py", line 1131, in create_bundle use_runtime_preference=use_runtime_preference File "/Library/Python/2.5/site-packages/py2app-0.5-py2.5.egg/py2app/ build_app.py", line 1120, in create_appbundle extension=self.extension, File "/Library/Python/2.5/site-packages/py2app-0.5-py2.5.egg/py2app/ create_appbundle.py", line 34, in create_appbundle copy(srcmain, destmain) File "/Library/Python/2.5/site-packages/py2app-0.5-py2.5.egg/py2app/ util.py", line 233, in mergecopy return macholib.util.mergecopy(src, dest) File "build/bdist.macosx-10.5-i386/egg/macholib/util.py", line 111, in mergecopy copy2(src, dest) File "build/bdist.macosx-10.5-i386/egg/macholib/util.py", line 43, in copy2 shutil.copy2(fsencoding(src), fsencoding(dst)) File "/System/Library/Frameworks/Python.framework/Versions/2.5/lib/ python2.5/shutil.py", line 91, in copy2 copyfile(src, dst) File "/System/Library/Frameworks/Python.framework/Versions/2.5/lib/ python2.5/shutil.py", line 46, in copyfile fsrc = open(src, 'rb') IOError: [Errno 2] No such file or directory: '/Library/Python/2.5/ site-packages/py2app-0.5-py2.5.egg/py2app/apptemplate/prebuilt/main- i386' > /System/Library/Frameworks/Python.framework/Versions/2.5/lib/ python2.5/shutil.py(53)copyfile() -> fsrc.close() I went into the Python Framework folder and the only prebuilt executeable in there is 32bit one, there isn't a main-i386 file.
