Python 2.7 not working anymore: cannot import name md5
提问by JulienCoo

我昨天在我的服务器上安装了 python 3.6.3（ubuntu 14.04），现在我无法运行 python 2.7（在虚拟环境和“主环境”上）。
I've been looking around google for this, without success.
我一直在寻找谷歌，但没有成功。

In this postmight be a solution:
在这篇文章中可能是一个解决方案：
The python2.7 package is dependent to the libssl1_0_0 package (openssl_1.0 runtime librairies).
python2.7 包依赖于 libssl1_0_0 包（openssl_1.0 运行时库）。
So you need to install it, and add the /usr/local/ssl/lib directory in $LD_LIBRARY_PATH environnent variable.
所以你需要安装它，并在 $LD_LIBRARY_PATH 环境变量中添加 /usr/local/ssl/lib 目录。
