pyaudio could not import _portaudio

Question

Trying to run python app that uses pyaudio. Using virtualenv and installations are working. However when running it can't find portaudio. But the _portaudio.so file exists. Any suggestions???

(venv) kidkic@pi-mirror1:~/audio $ jasper/jasper.py 
Could not import the PyAudio C module '_portaudio'.
Traceback (most recent call last):
  File "jasper/jasper.py", line 31, in <module>

    import pyaudio

    import _portaudio as pa
ImportError: /home/kidkic/audio/venv/local/lib/python2.7/site-packages/_portaudio.so: undefined symbol: Pa_GetStreamReadAvailable


# CHECKING THAT THE FILE EXISTS (a binary file)
(venv) kidkic@pi-mirror1:~/audio $ ls venv/local/lib/python2.7/site-packages/_*

The issue isn't that it can't find the library, but that the library is missing a function that is needed. (source code). I ran into the same problem, and believe the issue stems from building with the wrong version of portaudio-dev.

What you need to do:

1. Uninstall python-pyaudio with sudo apt-get purge --remove python-pyaudio if you have it (This is version 0.2.8)
2. Download the latest version (19) of PortAudio.
3. Untar and install PortAudio
   • ./configure
   • make
   • make install
4. Get the dependencies for pyaudio
   • portaudio19-dev
   • python-all-dev (python3-all-dev for Python 3)
5. sudo pip install pyaudio

After that, I was able to use pyaudio.
