Closed milyas122 closed 1 year ago

OSError: cannot load library 'gobject-2.0-0': error 0x7e. Additionally, ctypes.util.find_library() did not manage to locate a library called 'gobject-2.0-0'

WhyNotHugo commented 3 years ago

Can you provide the entire error/traceback?

This doesn't look like a library we import directly.

WhyNotHugo commented 2 years ago

weasyprint is failing to load gobject-2. Is it installed?

It seems that installing it on window it quite non-trivial, but there's some instructions here: https://doc.courtbouillon.org/weasyprint/v0.42.3/install.html#windows

See issues here if you have problems after following the above instructions: https://github.com/Kozea/WeasyPrint/issues?q=cannot+load+library+%27gobject-2.0-0%27%3A

WhyNotHugo commented 2 years ago

Actually, will leave open since the docs should point out that weasyprint's dependencies are required.

@WhyNotHugo I have another issue after install GTK3
