Help using Blabel

[coolyear123]

I've installed Blabel both with pip and by unzipping the source files but I still get an error in python when I try to do a test run. I don't know whats going on. Attached are the errors.

Sorry to hear that. It looks like the failure happens during Weasyprint import. You should visit their Github, you may find a solution there (please report back if you do! looks like a Windows/Weasyprint issue).

import os
# insert the GTK3 Runtime folder at the beginning
GTK_FOLDER = r'C:\Program Files\GTK3-Runtime Win64\bin'
os.environ['PATH'] = GTK_FOLDER + os.pathsep + os.environ.get('PATH', '')
from blabel import LabelWriter

Add the above before importing other libraries after installing GTK3 on windows. It worked for me.
