mediasoup-demo

Hello,

I am trying to install mediasoup-demo in ubuntu 20.04, node lts/gallium, python 3.8 and the installation fails with this log about a meson bug. Any idea about it will be appreciated. If you prefer screenshots for logs, please indicate to me.Thanks

sudo apt update -y
sudo apt upgrade -y

curl -sL https://deb.nodesource.com/setup_16.x | sudo -E bash - 

sudo apt install nodejs -y
sudo apt-get install build-essential -y
sudo apt install python3-pip -y
sudo apt update -y
sudo npm install pm2@latest -g
sudo npm install -g npm@latest
sudo reboot

npm install mediasoup --save

Try these steps, some things are missing at first. The build-essential and python3-pip are required in our case.

Thanks, it works for me. I think my mistake was to select the version for python instead of the one from repositories.

Kind regards,

Beka

No problem, whether this is uBuntu 20 → 22.xx it should work just fine, things may update but that’s for a different day.
