How to install pyaudio on openwrt

Hey guys, I'm trying to install pyaudio module for my project (using MT7688 hardware)
I use python 2.7
After command python -m pip install pyaudio, this error appear.
unable to execute 'ccache_cc': No such file or directory
Anyone can help me, i need this module to stream audio data from a MQTT broker
error: command 'ccache_cc' failed with exit status 1

using python with pip may need some build tools (like gnuc...) to compile needed packages

Thanks for your reply
In my case, could you let me know what I need to do to install pyaudio package

ccache, I suppose...
