Hi
I guess the zbar project is not supported since, it is not updated since 2009.

Try https://github.com/zplab/zbar-py
It is a simple zbar extension for python3

[Bastel Pichi]

For the archive:
sudo apt install python3-dev

If you are using other python versions:
sudo apt install python3.X-dev
For Python 3.9:
sudo apt install python3.9-dev
