'import rawread': frame not available

[XMUsuny]

Hello,
I just use the example to test librosa, using python3.7 on win10:

filename = librosa.util.example_audio_file()
y, sr = librosa.load(filename)

Result:FileNotFoundError: [WinError 2] 系统找不到指定的文件。

Librosa uses audioread to open audio file, then I find 'frame not available' when execute 'from . import rawread' in function 'available_backends()'. Could you tell me how to solve this question?

Thanks.
