使用pydub读取MP3文件时触发FileNotFoundError的解决方法

问题 #

使用pydub读取MP3文件时触发FileNotFoundError，已确认MP3文件路径正确，但仍报错。

代码如下：

from pydub import AudioSegment

AudioSegment.ffmpeg = r"C:\Users\תמרה\AppData\Local\ffmpegio\ffmpeg-downloader\ffmpeg\bin\ffmpeg.exe"

sound = AudioSegment.from_mp3(r"C:\Users\תמרה\PycharmProjects\spotify\The Moon Drops - Nathan Moore.mp3")

运行后错误信息：

"C:\Users\תמרה\PycharmProjects\spotify\file stuff.py" 
C:\Users\תמרה\PycharmProjects\spotify\venv\lib\site-packages\pydub\utils.py:170: RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work

解决方法 #

• 同时指定ffprobe路径：pydub处理音频时需要ffprobe获取媒体信息，你只设置了ffmpeg的路径，需补充ffprobe的路径（通常和ffmpeg在同一目录）：

  AudioSegment.ffprobe = r"C:\Users\תמרה\AppData\Local\ffmpegio\ffmpeg-downloader\ffmpeg\bin\ffprobe.exe"
  

• 规避路径中的特殊字符：你的用户名包含非英文字符，Windows部分程序对非ASCII路径支持不佳。建议将ffmpeg文件夹移到纯英文路径下，比如C:\ffmpeg\bin，再重新设置：

  AudioSegment.ffmpeg = r"C:\ffmpeg\bin\ffmpeg.exe"
  AudioSegment.ffprobe = r"C:\ffmpeg\bin\ffprobe.exe"
  

• 验证可执行文件存在性：直接在文件资源管理器中打开你指定的ffmpeg/ffprobe路径，确认.exe文件确实存在，路径拼写无错误。
• 简化MP3文件路径：将MP3文件复制到项目根目录，用相对路径读取，排除复杂路径的问题：

  sound = AudioSegment.from_mp3("The Moon Drops - Nathan Moore.mp3")
  

• 提升运行权限：右键点击PyCharm选择「以管理员身份运行」，避免权限不足导致无法读取文件或执行ffmpeg。
