Когда я пытаюсь запустить его, я получаю эту ошибку.

Вам не нужен импорт QtGui .

Большинство NameError: name 'foo' is not defined связаны с отсутствием импорта, когда ожидается, что foo будет библиотекой.

В вашем случае добавьте это:

from PyQt4 import QtGui

Я не знаю, есть ли у кого-то проблемы с кодом pyipchanger.py. Я игрок Tibia и начинающий программист. Я надеюсь, что кто-то другой найдет это полезным.

Я прокомментировал попытку и, кроме логики, которая обрабатывает Phonon, на строках 18-26. Вот как это должно выглядеть:

    #try:
    #    from PyQt4.phonon import Phonon
    #except ImportError:
    #    app = QtGui.QApplication(sys.argv)
    #    QtGui.QMessageBox.critical(None, "Music Player",
    #            "Your Qt installation does not have Phonon support.",
    #            QtGui.QMessageBox.Ok | QtGui.QMessageBox.Default,
    #            QtGui.QMessageBox.NoButton)
    #    sys.exit(1)    

Кроме того, я прокомментировал следующие коды, которые также связаны с фононом (строки 238-249).

    # Start thread
    self.thread.start() # not to comment this line.
    # if not self.musicService or not self.musicService.isRunning():
    #     self.musicService = MusicService()
    #     self.musicService.server = str(self.le.text())
    #     self.musicService.port = int(self.port.text()) + 10000
    #     for n in xrange(10):
    #         output = Phonon.AudioOutput(Phonon.GameCategory, self) 
    #         m_media = Phonon.MediaObject(self) 
    #         Phonon.createPath(m_media, output) 
    #         self.musicService.players.append(m_media)
    #     self.musicService.start()

Эти изменения устраняют исполнение Phonon и связанных с ним вещей. Я не знаю, как действительно работает Phonon.

Надеюсь, это поможет вам, ребята.

См. ya.
