gobject-introspection v1.80 compat error ("gi.RepositoryError: Typelib file for namespace 'GObject', version '2.0' not found")

[samtuke]

I'm getting this error on Mac M2 hardware today. I've been running gtimelog from git for months, not sure what's causing it. libx11 was upgraded also today, in case that's related by any chance. Ideas?

~/D/gtimelog (master)> gtimelog

During handling of the above exception, another exception occurred:

Hello,
I got the same error. It is actually the version 1.80 of gobject-introspection, which does not well with gtimelog.

My workaround was to downgrade to 1.78.1. If you use homebrew, those steps might help, as long no other dependency needs the new gobject-introspection version. I pinned the version in the last step to avoid another automatic upgrade.

brew info gobject-introspection
# Uninstall the old version. Alternatively `unlink` could also work.
brew uninstall gobject-introspection
curl -o gobject-introspection.rb  https://raw.githubusercontent.com/Homebrew/homebrew-core/abdcdb4613d762c58b0d59ae97f34e92e00f493d/Formula/g/gobject-introspection.rb
brew install -s gobject-introspection.rb
brew pin gobject-introspection

@sallner That worked! Awesome; thanks for taking the time to share 🙏

Not sure whether to close this (due to the workaround) or not... I'll change the issue name to make it more relevant for the future, and keep it open (maintainers: feel free to close instead, of course).

gi.RepositoryError: Typelib file for namespace 'GObject', version '2.0' not found

I'm not familiar with Homebrew, but this error means the GObject-2.0.typelib file is not installed. On Ubuntu it's provided by the gir1.2-glib-2.0 package and resides in /usr/lib/x86_64-linux-gnu/girepository-1.0/
