title: Errors installing PyAudio "Failed Building Wheel for PyAudio"
body: <p>I have been having trouble finding a fix for getting PyAudio installed on my machine. I have tried a few different solutions and i do have the prerequisite library "portaudio" installed using homebrew. I have also looked for solutions to the gcc error that appears at the bottom of the output and to which solutions only generated a different error that read "Error: command ‘clang’ failed with exit status 1". I feel at this point it is some lack of understanding of the implications of these error messages due to a lack of experience in python that keeps me from understanding a resolution. Any help is greatly appreciated. Thank you.</p>
