python - PyDub 找不到 mp3 文件 (Windows)

问题描述

我有以下代码在尝试查找 mp3 文件时出错。链接是准确的（copyfile 函数工作得很好），这让我相信这是一个 PATH 问题或 ffmpeg。任何想法是什么推动了这一点？

代码：

from pydub import AudioSegment
import pydub
from shutil import copyfile

pydub.AudioSegment.ffmpeg = r"C:\ffmpeg\bin\ffmpeg.exe"
pydub.AudioSegment.converter = r"C:\ffmpeg\bin\ffmpeg.exe"

copyfile(link, link2)
sound = AudioSegment.from_mp3(link)
second_half = sound[:30]
second_half.export(file2, format="mp3")

错误：
