Description
When installing zbarlight using pip, I get the following error, that I have been unable to find any information about. I use MacOS, Python3 and pip3.
I followed the install procedure, i.e. zbar was installed via homebrew.
The pip install of zbarlight finishes the install with this warning:
Running setup.py (path:/private/var/folders/gk/07t7dq7n01v45sj7k8295dqc0000gn/T/pip-build-di27kndu/zbarlight/setup.py) egg_info for package zbarlight produced metadata for project name unknown. Fix your #egg=zbarlight fragments.
The package is also not listed as zbarlight but as UNKNOWN in my pip list. It also doesnt show any documentation using "pip show".
When I install directly from source (download zip, then run setup.py) the same error occurs.
I can import the module in python (as zbarlight, not as UNKNOWN), but the command "zbarlight.scan_codes('qrcode', image)" gives the error
AttributeError: module 'zbarlight' has no attribute 'scan_codes'
Is there a known solution to this problem?
This is the verbose output of the pip install:
