使用Python播放声音

Question

基本上我正在尝试编写一个使用 python 打开声音文件的代码，但我得到的只是这个错误。使用 MacOS 和 Python 3.10。尝试了很多解决方案但没有成功。

这是我首先尝试过的代码：

from playsound import playsound
playsound('/Users/cairo/Desktop/i wish.mp3')

    /Users/cairo/PycharmProjects/pythonProject/venv/bin/python /Users/cairo/PycharmProjects/pythonProject/main.py 
playsound is relying on a python 2 subprocess. Please use `pip3 install PyObjC` if you want playsound to run more efficiently.
Traceback (most recent call last):
  File "/Users/cairo/PycharmProjects/pythonProject/main.py", line 3, in <module>
    playsound(r'/Users/cairo/Desktop/beep sound 2')
  File "/Users/cairo/PycharmProjects/pythonProject/venv/lib/python3.10/site-packages/playsound.py", line 244, in <lambda>
    playsound = lambda sound, block = True: _playsoundAnotherPython('/System/Library/Frameworks/Python.framework/Versions/2.7/bin/python', sound, block, macOS = True)
  File "/Users/cairo/PycharmProjects/pythonProject/venv/lib/python3.10/site-packages/playsound.py", line 223, in _playsoundAnotherPython
    raise PlaysoundException('Cannot find a sound with filename: ' + sound)
playsound.PlaysoundException: Cannot find a sound with filename: /Users/cairo/Desktop/beep sound 2

Process finished with exit code 1

我已经通过终端安装了 pip3 install PyObjC 但它一直显示错误。 似乎是什么问题？

编辑： 尝试过这个：

from pydub import AudioSegment
from pydub.playback import play

song = AudioSegment.from_wav("/Users/cairo/Desktop/i wish.mp3")
play(song)

这些是我得到的错误：

/Users/cairo/PycharmProjects/beepsound/venv/lib/python3.10/site-packages/pydub/utils.py:170: RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work

我将不胜感激任何帮助

也许 python 不是适合这项工作的 PL？

Answer 1

我遇到了同样的错误，并在 Mac 上解决了 - 您还需要安装 PyObjC

印有一行小字，上面写着 “playsound 依赖于 python 2 子进程。如果您希望 Playsound 更高效地运行，请使用

pip3 install PyObjC

。” 截图

如果你安装了PyObjC，它就可以成功运行。

Answer 2

不是问题的解决方案，而是替代方案。 我遇到了同样的问题，playsound 似乎被破坏了，因为它依赖于 python 2.7。

您可以使用 pydub 作为替代方案。

from pydub import AudioSegment
from pydub.playback import play

song = AudioSegment.from_wav("path/to/file.wav")
play(song)

Answer 3

我认为你应该使用 pygame 来播放声音

https://www.pygame.org/wiki/GettingStarted

pip3 install pygame

pygame.mixer.init()
pygame.mixer.music.load("file.mp3")
pygame.mixer.music.play()

Answer 4

免责声明：

我建议您使用

nava

代替。 您只需通过以下方式安装即可：

pip install nava

然后通过以下方式播放声音：

from nava import play
play('/Users/cairo/Desktop/i wish.mp3')
