I gonna install pyaudio and sounddevice packages via requirements.txt in EC2. But it says raise OSError('PortAudio library not found') So I tried to install libasound-dev for sounddevice...

Yum install libasound-dev

But it also said :

No package libasound-dev available

How should I do? I am in AWS EC2.

CodePudding user response：

libasound-dev is for Ubuntu. For Amazon Linux 2 it should be:

sudo yum install alsa-lib-devel

For portaudio:

sudo amazon-linux-extras install epel -y
sudo yum install -y portaudio-devel portaudio

CodePudding user response：

If you are in Window and gonna use pyaudio, you would use like this:

pip install pipwin
pipwin install pyaudio

This works well on Window.
