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.

Answer 1

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
