Learn how install properly PyAudio in Ubuntu 18.04 and prevent this exception from appearing.

Usually, you will be able to install PyAudio with PIP using the following command:

pip install PyAudio

Pitifully, in some distributions of Ubuntu, you will face an exception about a failure when building the wheel for pyaudio. According to the Python Packaging Index’s description, a wheel *is designed to contain all the files for a PEP 376 compatible install in a way that is very close to the on-disk format.


The error output when you try to install the package will be:

pip install pyaudio
Failed building wheel for pyaudio
  Running setup.py clean for pyaudio
Failed to build pyaudio

  Running setup.py install for pyaudio ... error

    #include "portaudio.h"

    error: command 'clang' failed with exit status 1

The error is basically caused by the missing portaudio.h file in the system. PortAudio is a free, cross-platform, open-source, audio I/O library.


You can fix this exception installing the dev portaudio package and pyaudio with the following command in Ubuntu:

sudo apt-get install portaudio19-dev python-pyaudio

Finally install the package again with the command:

pip install PyAudio

And you should be able to install it properly without an issue !
