如何在Python中将wav文件转换为mp3文件？我找到的唯一答案是使用“pydub”，但它对我根本不起作用：

from pydub import AudioSegment
AudioSegment.from_wav("myfile.wav").export("myfile.mp3", format="mp3")

错误结果：

CouldntEncodeError: Encoding failed. ffmpeg/avlib returned error code: 1

Command:['ffmpeg', '-y', '-f', 'wav', '-i', 'C:\\Users\\user\\AppData\\Local\\Temp\\tmp4bj663tf', '-f', 'mp3', 
'C:\\Users\\user\\AppData\\Local\\Temp\\tmp0kadz5q2']

文件路径是正确的（否则我有一个不同的错误），我已经尝试了频率从50k到5k的输入信号，同样的错误。
正在搜索另一种转换方法或修复此问题。
