我发现自己在墙前,只是试图将音频文件加载到pydub中进行转换,这会不断引发“[Errno 2] No such file or directory”错误。

自然,我花了太多时间来确保路径有效,尝试了相对路径和绝对路径,并确认python方法open()在完全相同的路径下可以正常工作。

我正在通过ubuntu上的anaconda 2.3 distrib在python 2.7的ipython 3.2中工作。

from pydub import AudioSegment
sound = AudioSegment.from_mp3("/absolute/path/to/file.mp3")

也尝试在路径中不带空格,因为有时这是一个问题。这是完整的错误日志:

OSError: [Errno 2] No such file or directory

我对这里真正简单的事情视而不见还是...?

编辑:
我还尝试按照Vaulstein的要求将路径作为原始文本r“/absolute/path/to/file.mp3”传递-这给了我同样的错误。

最佳答案

异常(exception)与您提供的文件名无关。查看回溯,找不到conversion_command调用的subprocess.Popen。反过来,这也可以解释以下警告:找不到avconvffmpeg。解决方案应该是在控制台中安装带有sudo apt-get install libav-tools的libav-tools软件包。

关于python - Pydub from_mp3提供[Errno 2]没有这样的文件或目录,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/34196195/
