Python 2.7不再工作:无法导入名称md5

Question

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envs和'main env'上).

我一直在寻找谷歌,没有成功.

当我变红时,我试图重新安装openssl.

谁能帮我 ？我疯了.

--->每当我试图执行python脚本(或pip)时,这是消息:

Answer 1

我在 macOS 上遇到了同样的问题。

brew reinstall python@2 解决了这个问题。

也许您可以尝试重新安装python。

Answer 2

在这篇文章中可能有一个解决方案：

python2.7包依赖于libssl1_0_0包（openssl_1.0运行时库）。

所以你需要安装它，并将 /usr/local/ssl/lib 目录添加到 $LD_LIBRARY_PATH 环境变量中。
