J'ai un problème lors du déploiement de l'application Flask sur l'instance AWS EC2. Probablement avec pip en installant lxml. Mais je ne sais pas comment résoudre le problème.Exigences obligatoires.txt lors du déploiement sur AWS. Pip n'a pas pu installer lxml
AWS EC2:
Platform: 64bit Amazon Linux 2015.03 v1.4.6 running Python 2.7
De CLI sur eb create:
