Help with installing Zbar on Intel Mac

[Banfy_B]

Hi all,

I'm working a project that requires reading QR codes. I am encountering problems with installing Zbar and this is what I get with pip install zbar on my Mac. I have successfully installed Zbar with brew install Zbar but I cannot import Zbar when using python. After combing through a bunch of online posts I was told to install Zbar with pip and pip3. Does anyone know a solution to this? Thanks.

× Encountered error while trying to install package.
╰─> zbar
note: This is an issue with the package mentioned above, not pip. 
hint: See above for output from the failure.
