    Perhaps you should add the directory containing `py3cairo.pc'
    to the PKG_CONFIG_PATH environment variable

I haven't been able to reproduce this with Python 3.9 and PyGObject 3.38.0. Given that it's been many months, I'll assume it's fixed and close this issue, but please feel free to reopen it or create another issue if you still encounter problems.

This is happening to me in Python 3.10.4

[taylordotfish]

@ashr123 Could you provide some additional system details (OS/distro type and version, processor architecture, the exact command you're running, etc.)?

[ashr123]

@taylordotfish I encountered it on my Raspberry Pi 4B, Ubuntu 22.04 64 bit. I've solved the problem by installing the package python3-cairo-dev

[electron-farmer]

Ditto. Just happened to me on Pop!_OS 22.04 LTS.
