Re: [Pyobjc-dev] Failed to run the HotKey Example

[Ronald O. <ron...@ma...>]

Hi,

This example like all pyobjc examples with a setup.py file needs to be run from an application bundle (run "python setup.py -A").

This particular example has some other restrictions (which aren't documented on the website right now):

* It requires python 2.x because it uses the Carbon package that was removed in Python 3.0

* It requires a 32-bit build of python 2.x because the Carbon package is ancient and uses functions that Apple hasn't made available in 64-bit code.  

The last restriction makes using py2app harder, because the app bundle will happily try to run in 64-bit mode when you build using a python that supports 64-bit code. The easiest workaround is to disable 64-bit through the finder (for this application).

I'm not sure why the application gives an ImportError exception when you try to run it. The usual problem is that the python you're using to run py2app is a different one than you expect (e.g. one without pyobjc installed), but that doesn't seem to be the problem here because you don't get an ImportError when running the script from the command-line.

P.S. I haven't tried to run this example in a long while, I'll try to do so tonight.

Hi,

I was trying to run the sample PyObjc HotKey example app downloaded from this link: http://pythonhosted.org/pyobjc/_downloads/PyObjCExample-HotKeyPython.zip

(My environment: Mac OS X 10.8.5, Python 2.7.5)

After I unpacked the file, I tried to:

1) run it via:

python HotKey.py

and got the following error:

Traceback (most recent call last):
  File "HotKey.py", line 18, in <module>
    from Carbon.CarbonEvt import RegisterEventHotKey, GetApplicationEventTarget
ImportError: cannot import name RegisterEventHotKey

2) run it in 32bit mode, as I thought this might only be supported in 32bit.

arch -i386 python HotKey.py

and got another error:

2014-01-03 21:57:41.083 Python[2047:f0b] No Info.plist file in application bundle or no NSPrincipalClass in the Info.plist file, exiting

3) Then I thought I might have to package it as an xx.app to run, then I executed the following command to package it:

python setup.py py2app -A

(also tried 'arch -i386 python setup.py py2app -A')

The app couldn't be run, and then ran it from console, I got the following errors:

Traceback (most recent call last):
  File "/Users/jiakuanwang/opensource/PyObjCExample-HotKeyPython/dist/HotKey.app/Contents/Resources/__boot__.py", line 69, in <module>
    _run()
  File "/Users/jiakuanwang/opensource/PyObjCExample-HotKeyPython/dist/HotKey.app/Contents/Resources/__boot__.py", line 62, in _run
    exec(compile(source, script, 'exec'), globals(), globals())
  File "/Users/jiakuanwang/opensource/PyObjCExample-HotKeyPython/HotKey.py", line 16, in <module>
    from AppKit import *
ImportError: No module named AppKit
2014-01-03 22:00:41.775 HotKey[2126:707] HotKey Error

Is it possible to run it in some way? Thanks in advance!

Thanks,
Jake
