Я пытался установить pycairo с pip3 на MacO, но всякий раз, когда вы пытаетесь это сделать, появляется эта ошибка:
pip3 install pycairo

Package libffi was not found in the pkg-config search path.
Perhaps you should add the directory containing `libffi.pc'
to the PKG_CONFIG_PATH environment variable
Package 'libffi', required by 'gobject-2.0', not found
Command '['pkg-config', '--print-errors', '--exists', 'cairo >= 1.13.1']' returned non-zero exit status 1.

Я установил cairo и pkg-config, используя brew.
Обновление, я установил путь к PKG_CONFIG_PATH, используя следующую команду
export PKG_CONFIG_PATH=/usr/local/Cellar/libffi/3.2.1/lib/pkgconfig/
И позже, используя pip3 для установки pycairo, он выполняет свою работу. Единственное, что, даже если он установлен сейчас, python3 не находит pycairo.
