Как установить cairocffi через pip?
cairocffi - это замена на основе CFFI для Pycairo https://github.com/SimonSapin/cairocffi.
Я пытаюсь установить его на Ubuntu 14.04:
[email protected]:~$ cat /etc/*-release

Как предложил @MattDMo, я пробовал apt-get install libffi, но он все еще не работал:
[email protected]:~$ sudo apt-get install libffi libffi-dev

E: Unable to locate package libffi
Но в менеджере пакетов нет libffi, поэтому я пробовал libffi-dev:
