python – 如何获得PyAudio 0.2.11版本

我尝试过使用该命令

sudo pip install PyAudio

但它似乎没有用.

Traceback (most recent call last):
    File "bingtest.py",line 8,in <module>
     m = sr.Microphone()
    File "/usr/local/lib/python2.7/dist-
  packages/speech_recognition/__init__.py",line 79,in __init__
      self.pyaudio_module = self.get_pyaudio()

  version {})".format(pyaudio.__version__))
