Als @MattDMo vorgeschlagen, ich habe apt-get install libffi versucht, aber es hat immer noch nicht funktioniert:

[email protected]:~$ sudo apt-get install libffi libffi-dev 
Reading package lists... Done 
Building dependency tree  
Reading state information... Done 
E: Unable to locate package libffi

Aber Es gibt keine libffi auf dem Paket-Manager, also habe ich versucht libffi-dev:

Wie gesagt, Sie müssen den Paketmanager Ihrer Linux Distribution ('yum',' apt-get', was auch immer) verwenden, um die Systempakete 'libffi' und' libffi-dev' zu installieren. Entschuldigung, wenn das nicht ganz klar war. – MattDMo

Wenn Sie das nächste Mal ein Problem oder eine Frage zu einer Antwort haben, können Sie unter der Antwort einen Kommentar abgeben, anstatt nur Ihre Frage zu bearbeiten, auch wenn es nur auf die Bearbeitung verweist. Ich habe das nur gesehen, weil ich versehentlich den Tab offen gelassen habe. Das Kommentieren sendet eine Benachrichtigung an den Autor und jeden, den Sie "@" erwähnen können. – MattDMo

Es ist direkt in der Fehlermeldung:

No package 'libffi' found

Sie werden libffi und libffi-dev installieren müssen über den Paketmanager Ihrer Distribution (yum, apt-get, was auch immer), bevor die pip Installation funktioniert. Ihre Namen können von Plattform zu Plattform sehr leicht variieren.

Auf Ubuntu sind die Pakete ['libffi6'] (http://packages.ubuntu.com/trusty/libffi6) und [' libffi-dev'] (http://packages.ubuntu.com/trusty)/libffi-dev). Running 'sudo apt-get installieren libffi6 libffi-dev' sollte gut funktionieren ... – MattDMo

Für mich, unter Windows 10 mit Python 3.5.3rc1, pip install cairocffi war fehlgeschlagen. Doing pip install cffi war ausreichend, um erfolgreich zu sein.
