Question

我对python很陌生，我对此进行了一些研究，但我发现的答案似乎不起作用。我试图用带有绝对路径的pyglet加载一个mp3文件，但它给出了这个错误：

Traceback (most recent call last):
  File "C:\Apps\Python\lib\site-packages\pyglet\resource.py", line 624, in media
    location = self._index[name]
KeyError: 'C:/Users/Ruurd/Google Drive/Script/Python/music2.mp3'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:/Users/Ruurd/Desktop/playmus.py", line 3, in <module>
    music=pyglet.resource.media(path)
  File "C:\Apps\Python\lib\site-packages\pyglet\resource.py", line 634, in media
    raise ResourceNotFoundException(name)
pyglet.resource.ResourceNotFoundException: Resource "C:/Users/Ruurd/Google Drive/Script/Python/music2.mp3" was not found on the path.  Ensure that the filename has the correct captialisation.

当我使用＆＃39; music2.mp3＆＃39;作为一条路径，它工作正常。这是无效代码

import pyglet
path='C:/Users/Ruurd/Google Drive/Script/Python/music2.mp3'
music=pyglet.resource.media(path)
music.play()

Answer 1

尝试使用：

music=pyglet.media.load(path)

而不是：

music=pyglet.resource.media(path)

为我工作。 =）

Answer 2

import pyglet
from os.path import abspath, isfile

pyglet.options['audio'] = ('directsound', 'alsa', 'openal', 'silent')

path = abspath('C:/Users/Ruurd/Google Drive/Script/Python/music2.mp3')
if isfile(path):
    music = pyglet.resource.media(path)
    music.play()

由于你不能在任何地方找到你的mp3，我无法对此进行测试但使用abspath来确保语法正确并使用isfile来确定该路径上是否存在该文件通常是个好主意。

要更好地控制所使用的驱动程序，可以使用pyglet.options['audio']来指定pyglet，例如directsound。

Pyglet使用绝对路径加载资源
