Python wsgi:ssl-error无法连接到HTTPS URL,因为SSL模块不可用

Question

我刚从Amazon ec2实例迁移到DigitalOcean droplet.在配置我的python应用程序,WSGI和apache2时遇到SSL问题,一切似乎都运行正常.

Droplet:Ubuntu 16.04 Python版本:2.7.12

我的应用程序使用python requests模块发出GET请求.请求返回500,当我检查我的日志时,我可以看到

我搜索了很多.我试过安装openssl,其他conf,但真的很沮丧.我不知道它如何在亚马逊ec2中顺利运行,但在Droplet中却不行.

任何有关良好方向的帮助都将受到赞赏.谢谢

Answer 1

如果您从源代码安装了Python,则必须重新运行

./configure
make
sudo checkinstall

安装openssl之后(我正在假设sudo apt install openssl).

Answer 2

我认为我安装的 python 版本有问题。要么安装了多个 python 版本，要么构建未正确构建。我的是Ubuntu 16.04 digitalOcean machine没有python安装的。所以我必须手动安装它。我按照https://askubuntu.com/questions/101591/how-do-i-install-python-2-7-2-on-ubuntu上给出的答案进行操作

但是，似乎没有任何作用。

最后，我创建了一台全新的机器，但这一次，它Ubuntu 14.04已经python安装好了。当我安装依赖项并部署 Flask 应用程序时，它工作正常。

将 Ubuntu 16.04（不带 python）更改为 Ubuntu 14.04（安装了 python）。
