Could not find a version that satisfies the requirement django==1.10.3 (from -r /home/bae/run/baeng/helios/work/appid9f0jy29yct/requirements.txt (line 1)) (from versions: )
No matching distribution found for django==1.10.3 (from -r /home/bae/run/baeng/helios/work/appid9f0jy29yct/requirements.txt (line 1))

百度这个问题说要解决需要安装openssl等软件包，但是通过SSH连接服务器我没有权限无法安装，而通过requirements.txt安装又会报错，如何解决？

Ce problème est souvent rencontré dans l'ancien Python. Il est probablement plus difficile à contrôler dans BAE. Il semble que seule la méthode d'installation Requirements.txt soit fournie.

pip utilise la bibliothèque urllib3 lors de l'installation de modules à partir de sources https. Le module ssl avant python2.7.9 est relativement ancien et entraînera des problèmes de sécurité avec les connexions SSL [1].
Il existe deux manières de résoudre directement ce problème :

1. Mettre à niveau Python vers une version supérieure à 2.7.9

2. Installer les dépendances de sécurité de urllib3【2】

   >> pip install pyopenssl ndg-httpsclient pyasn1
   

Vous pouvez également utiliser directement la source http pour éviter ce problème, comme :

  >> pip install django==1.10.3 -i http://pypi.douban.com/simple
