Не удалось установить зависимость от Bluemix с личной настройкой pypiserver

Question

Я пытаюсь нажать приложение Django python в Bluemix.

Я использую некоторую глобальную зависимость и личный пакет, который имеет некоторую глобальную зависимость.

Мое приложение работает хорошо, когда я просто добавляю свой личный пакет в папку приложения.

e.g.in requirements.txt:

Mezzanine==4.1.0 
cartridge 
Django==1.9.7 
-r ./my_personal_package/requirements.txt 

в ./my_personal_package/requirements.txt:

pyOpenSSL==16.0.0 
requests==2.9.1 
psutil==4.3.0 

Но, если я пакет мой личный пакет как PyPi пакет с пип инструментом. и поставить его на личный сервер pypi, доступ к которому может получить bluemix. Мое приложение не будет запущено. он потерпел неудачу на установке cffi пакета (сообщение об ошибке добавляемых в конце этого вопроса)

мой requirements.txt выглядит следующим образом:

-extra-index-url https://mypypiserver.mybluemix.net/repos/simple/ 
my-personal-package 
Mezzanine==4.1.0 
cartridge 
Django==1.9.7 

Я сравнил пакеты, загруженные с помощью метода 1 и метода 2, то они точно такие же. Метод 2 только не на установке cffi:

Answer 1

Установка cffi не удалось из-за "Нет 'пакета libffi' найден". «libffi», как известно, беспорядочен для установки и использования. Поскольку вы используете пакеты зависимости от размещения pypi-сервера, первое, что я хотел бы проверить, - правильно ли настроен сервер в соответствии с cffi installation instructions.
