Cercando di usare Pyglet - cosa significa questo errore?

Question

Sono in esecuzione Mac OS X Mountain Lion, con Python 2.7. Ho fatto un'installazione sorgente di Pyglet che sembrava andare senza errori, ma ogni volta che provo a eseguire un programma ottengo un errore piuttosto lungo che non capisco. Sembra che abbia qualcosa a che fare con QuickTime ??

Ogni programma che ho provato dà lo stesso errore. I programmi che ho provato in esecuzione sono gli esempi che è venuto nella fonte e l'esempio qui: http://guzalexander.com/2012/08/17/playing-a-sound-with-python.html

L'errore che ottengo dice:

Answer 1

ho fatto un po 'di googling, e alla fine ho trovato una pagina che affronta questo errore. Apparentemente il problema è che a Pyglet non piacciono le architetture a 64 bit. Queste istruzioni fissati per me: http://roguejs.com/2011-11-22/getting-pyglet-to-work-on-mac-osx-lion/

Getting pyglet to work on Mac OSX Lion

November 22, 2011 by roguejs

For those of you who wanted to start doing game development in Python and wanted to use pyglet for it, and you’re using Mac OSX Lion, you’ll most probably come across this error:

OSError: dlopen(/System/Library/Frameworks/QuickTime.framework/QuickTime, 6): no suitable image found. Did find: /System/Library/Frameworks/QuickTime.framework/QuickTime: mach-o, but wrong architecture /System/Library/Frameworks/QuickTime.framework/QuickTime: mach-o, but wrong architecture Do not fret – this is merely pyglet 1.1.4 choking on 64-bit architectures (interesting trivia: Pyglet 1.1.4 is currently using the Carbon API, while Pyglet 1.2 is supposed to be ported over to use Cocoa instead).

The easiest way to do this is to force python to go 32bit by typing this in your console:

defaults write com.apple.versioner.python Prefer-32-Bit -bool yes However, just to be safe, I’m going to go through the entire setup steps in case you find any problems with it. Here goes:

Step 1 – install Mercurial in your Mac

Go to Mercurial and download the latest binary for your Mac. Install it, and then open the terminal.

Step 2 – clone the pyglet repository

Create a directory (I did mine in ~/Projects/lib), and clone the pyglet repository into it:

hg clone https://pyglet.googlecode.com/hg/ pyglet

cd pyglet

Step 3 – build it

Now in this step, you can optionally switch to the cocoa-port branch and try it out. Didn’t work for me though.

Optional

hg checkout cocoa-port

Build it

python setup.py install

Step 4 – Force python into 32-bits

Once you’re done, force python into 32 bits with this command:

defaults write com.apple.versioner.python Prefer-32-Bit -bool yes And that’s it! Try building your pyglet app now – they shouldn’t throw the same exception again.

Answer 2

Simile alla precedente, l'installazione di mia ha fatto il trucco migliore. Ho adattato le istruzioni che ho trovato su questo sito: http://twistedpairdevelopment.wordpress.com/2012/02/21/installing-pyglet-in-mac-os-x/

Tutto quello che dovevo fare era usare pip per installare direttamente dal repository.

pip install hg+ https://pyglet.googlecode.com/hg/

Lavoro fatto.
