but again get another

fatal: destination path 'pyaudio' already exists and is not an empty directory.

Can you please guide me that how do I install PyAudio in RaspberryPi

Answer

Remove the directory PyAudio which already presen in /home/pi and then try these steps

sudo apt-get install git

sudo git clone http://people.csail.mit.edu/hubert/git/pyaudio.git
