In case anyone ends up here like I did, there’s some awful pip behavior on display.

If you install cairocffi with a version of setuptools that’s too old, pip will build cairocffi with that old setuptools, producing a broken build with this nonsense version number, and then it will upgrade setuptools because it knows cairocffi doesn’t work with the old one. But you’ll still have the broken build.

And it’s actually even worse: if you uninstall and reinstall cairocffi with the upgraded setuptools, you’ll still get the broken build because pip cached it. For me, doing rm -rf ~/.cache/pip fixed that.

This issue caused Weasyprint to not install for me citing that it needed a version of cairocffi >= 0.9.0. For the time being I fixed the issue by specifying the version for cairocffi to be 1.0.0 in requirements.txt.
