Pyaudio Installation failure on Ubuntu [duplicate]

Question

Pyaudio Installation failure on Ubuntu I have ubuntu 18LTS python 2 and python 3 pip 10

I installed libportaudio2 and libasound-dev from suggestions I found on google. Is it because I need to install other libraries as well?

Here is the error I got I tried the sudo -H flag but no difference.

sudo python -m pip install pyaudio
The directory '/home/ec2/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

Answer 1

fatal error: portaudio.h: No such file or directory

you are missing some build dependencies, so it fails compilation. specifically, the error shows it can't find portaudio.h, which comes with the portaudio19-dev package.

so install the required headers with:

sudo apt-get install portaudio19-dev

then try your pip install.
