ImportError: Unable to find dmtx shared library (Mac)

[guglie]

On MacOSX it doesn't works. Following the installation guide I run

pip install pylibdmtx
brew install libdmtx

Then:

from PIL import Image
decode(Image.open('<image-path>'))

But it says ImportError: Unable to find dmtx shared library

I also tried to add the brew cellar to the path without success.

I'm running python 3.11 on macOS 13.1 - and was having the same issue.

After some debugging I fixed this by adding a symlink to one of the locations it was searching for the library

sudo ln -s /opt/homebrew/lib/libdmtx.dylib /usr/local/lib/

And just in case /usr/local/lib doesn't exist, create it first!

sudo mkdir /usr/local/lib/
sudo ln -s /opt/homebrew/lib/libdmtx.dylib /usr/local/lib/
