Jak zainstalować pakiet cffi na AWS Beanstalk

Question

To pytanie wygląda tak samo, jak this post, ale ponieważ nie było odpowiedzi, ponownie pytam.

Mam projekt Django do wdrożenia na AWS Beanstalk, który używa pakietu cffi. Kiedy uruchamiam eb deploy, dzienniki błędów wygląda:

mogę powiedzieć, że AWS szuka libffi bez powodzenia. Jak jednak to zainstalować? Próbowałem obejścia w powyższym linku, ale nie działa również.

Answer 1

Aby zainstalować pakiet cffi Pythona, trzeba najpierw zainstalować libffi-devel użyciu yum:

sudo yum install libffi-devel 

które można zautomatyzować, dodając je do pliku config w folderze .ebextensions tak:

packages: 
    yum: 
     libffi-devel: [] 

Zostało to wspomniane w innym post, ale ponieważ wyszukiwarka przyniosła mi tutaj pierwszy, a drugi jest oznaczony jako duplikat ... myślałem Powinienem lepiej tu odpowiedzieć.
