i am using pyzbar which requires the zbar shared library as it's dependency.....how can i install it??
and also trying to download any package from the package installer doesn't seems to work.
Maybe try it with a Nix repl…??
Create A Repl > Nix > replit.nix
Something like that. They provide a tutorial to nix in each Nix repl you make, so you’ll figure it out pretty easily.
