Come si installa cairocffi tramite pip?Come installare pip cairocffi?

cairocffi è una sostituzione drop-in basata su CFFI per Pycairohttps://github.com/SimonSapin/cairocffi.

Sto cercando di installarlo su Ubuntu 14.04:

ho controllato manualmente il permesso e ho capito che non esiste un permesso di accesso in scrittura. Perché è così? E perché sudo non sta lavorando per sovrascrivere il permesso?

Come suggerito @MattDMo, ho provato apt-get install libffi ma ancora non ha funzionato:

[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

Ma non c'è alcun libffi sul gestore di pacchetti, quindi ho provato libffi-dev:

Si installa libffi-dev successo ma cairoffi non è ancora l'installazione:

Come ho già detto, è necessario utilizzare il gestore di pacchetti della propria distribuzione Linux ('yum',' apt-get', qualsiasi cosa) per installare i pacchetti di sistema 'libffi' e' libffi-dev'. Scusa se non era perfettamente chiaro. – MattDMo

Inoltre, la prossima volta che hai un problema o una domanda su una risposta, potresti commentare la risposta anziché semplicemente modificare la tua domanda, anche se è solo per indicare la modifica? L'ho visto solo perché ho lasciato per sbaglio la linguetta. Il commento invia una notifica all'autore e chiunque tu possa "@" menzionare. – MattDMo

E 'proprio nel messaggio di errore:

No package 'libffi' found

avrete bisogno di installare libffi e libffi-dev tramite il gestore pacchetti della distro (yum, apt-get, qualsiasi altra cosa) prima che l'installazione di pip funzioni. I loro nomi possono variare leggermente da una piattaforma all'altra.

@alvas quale distro e versione usi? – MattDMo

+0

è ubuntu 14.04 – alvas

Su Ubuntu i pacchetti sono ['libffi6'] (http://packages.ubuntu.com/trusty/libffi6) e [' libffi-dev'] (http://packages.ubuntu.com/trusty/libffi-dev). L'esecuzione di 'sudo apt-get install libffi6 libffi-dev' dovrebbe funzionare bene ... – MattDMo

Per me, su Windows 10 utilizzando python 3.5.3rc1, pip install cairocffi non funzionava. Fare pip install cffi è stato sufficiente per farcela.
