Python Librosa can'；无法识别文件（.wav、.mp3）Pycharm MacOS

我想用Pycharm和librosa一起绘制某种类型音频文件的波形，但在加载文件时遇到了麻烦。当我开始运行它时，出现以下错误：

/Users/username/Desktop/example/venv/lib/python3.7/site-packages/librosa/core/audio.py:162: UserWarning: PySoundFile failed. Trying audioread instead.
warnings.warn("PySoundFile failed. Trying audioread instead.")
    Traceback (most recent call last):

    RuntimeError: Error opening 'audiofile.filetype': System error.
    
    During handling of the above exception, another exception occurred:

        y, sr_native = __audioread_load(path, offset, duration, dtype)

        self._fh = open(filename, 'rb')
    FileNotFoundError: [Errno 2] No such file or directory: '2 octaves.mp3'
    
    Process finished with exit code 1

我试着将return

subprocess.Popen（cmd，*args，**kwargs，shell）

替换为

return subprocess.Popen（cmd，*args，**kwargs，shell=True）

in

ffdec.py

inaudioread

如果你知道如何解决这个问题，请帮助我和评论下面，谢谢

import librosa as lr
import librosa.display as ld
import matplotlib.pyplot as plt

# load mp3 doc
y, sr = lr.load('2 octaves.mp3', sr=None)

# plot a mp3form
plt.figure()
ld.waveplot(y, sr)
plt.title('Beat mp3form')
plt.show()
