How do I install "pygobject" and "pycairo" in Python?

[frozen905]

Hello all! I am getting warnings about needing pygobject so I tried to install it And this is what happened

I first include the output showing wheel is updated and setuptools fully installed

~ $ pip install --upgrade wheel

So I see it talks about pycairo which also fails

And something called xproto which it says no such package

Thanks for any help ❤️🇨🇦

Found some old conversation on Google search and figured it out 🤗

xproto is in pkg install xorgproto which then allows pip install pycairo to complete no problem

pip install pygobject now has new errors

It's complaining about something called gobject-introspection which I install with pkg install gobject-introspection

After this is installed I can finally complete pip install pygobject successfully!
