import soundfile报错：OSError: sndf

报错

Traceback (most recent call last):

  File "prepare_data.py", line 9, in <module>

    import soundfile

  File "/usr/local/lib/python2.7/dist-packages/soundfile.py", line 142, in <module>

    raise OSError('sndfile library not found')

OSError: sndfile library not found

以为是版本问题，重装之后报错

报错原因

缺少libsndfile，查看 SoundFile官网，发现需要安装libsndfile

 On Linux, you need to install libsndfile using your distribution’s package manager, for example sudo apt-get install libsndfile1.

解决办法

sudo apt-get install libsndfile1

（之前用的时候直接pip install soundflie 就可以了，不记得有这一步。。。）
