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

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:
Uninstall python-pyaudio with sudo apt-get purge --remove python-pyaudio if you have it (This is version 0.2.8)
Download the latest version (19) of PortAudio.
Untar and install PortAudio
./configure
make install
Get the dependencies for pyaudio
portaudio19-dev
python-all-dev (python3-all-dev for Python 3)
sudo pip install pyaudio
After that, I was able to use pyaudio.

For linux users you may get something like this after you install portaudio
Libraries have been installed in:
/usr/local/lib
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------
PortAudio was successfully installed.
On some systems (e.g. Linux) you should run 'ldconfig' now
to make the shared object available. You may also need to
modify your LD_LIBRARY_PATH environment variable to include
the directory /usr/local/lib
So, I would like to add the below commands as step number 4, following the steps in above answer by Wehrdo.
sudo ldconfig
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
echo "export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/your/custom/path/" >> ~/.bashrc
when I install pyaudio with conda, the error comes out. However, it is gone when I just install it with pip by 'pip install pyaudio'
It seems like a problem in the conda source of this package.
The problem is that portaudio and pyaudio are mainly supported for python 2.7, 3.4, 3.5 and 3.6 as of now. At the time you asked the question 2.7 probably wasn't supported. You always have to check this website: https://pypi.org/project/PyAudio/#files if you want to know which versions of python are compatible. If you want to keep your version of python the same, try this unofficial site for Windows: https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyaudio
