問題導入 python 聲音文件庫 - OSError: library not found: 'sndfile'

Question

我正在托管一個使用 soundfile 庫進行音頻計算的 python Flask 服務。 它在我的本地運行良好，但是當我在 redhat 上托管它時，我看到了以下問題。 有什么建議 -

 from soundfile import read
  File "/apollo/env/AQTAudioPoProService/lib/python3.4/site-packages/soundfile.py", line 265, in <module>
    _snd = _ffi.dlopen('sndfile')
  File "/apollo/env/AQTAudioPoProService/lib/python3.4/site-packages/cffi/api.py", line 139, in dlopen
    lib, function_cache = _make_ffi_library(self, name, flags)
  File "/apollo/env/AQTAudioPoProService/lib/python3.4/site-packages/cffi/api.py", line 769, in _make_ffi_library
    backendlib = _load_backend_lib(backend, libname, flags)
  File "/apollo/env/AQTAudioPoProService/lib/python3.4/site-packages/cffi/api.py", line 757, in _load_backend_lib
    raise OSError("library not found: %r" % (name,))
OSError: library not found: 'sndfile'

嘗試安裝 libsndfile

No package libsndfile available.

libsndfile Python 模塊依賴於libsndfile本地庫。 您需要在您的操作系統上安裝它：

$ yum install libsndfile
