Question

我尝试使用 Pydub ，我想将mp3文件转换为wav，已经告知{{3} }}。

即使文件存在，我也会收到No such file or directory的错误。

这是我的代码：

import os.path
print "File Present:", os.path.isfile('/home/nikhil/Documents/Python/IPython Notebooks/test.mp3') 

from pydub import AudioSegment
sound = AudioSegment.from_mp3('/home/nikhil/Documents/Python/IPython Notebooks/test.mp3')
sound.export("file.wav", format="wav")

这是完整的日志猫：

File Present: True

OSError: [Errno 2] No such file or directory

（请忽略错误的格式。我更喜欢这种方式（缩进））

这里出了什么问题？

Answer 1

修改

我刚看到有同样问题的人，这是因为他们没有安装ffmpeg库。尝试：

sudo apt-get install ffmpeg

或

sudo apt-get install libav-tools

Answer 2

您的路径在Popen函数中用作参数，如您的回溯显示。

尝试添加其他引号：

sound = AudioSegment.from_mp3('"/home/nikhil/Documents/Python/IPython Notebooks/test.mp3"')

＆＃34; OSError：[Errno 2]没有这样的文件或目录＆＃34;转换mp3
