Question

在更新到Ubuntu 18.04 LTS之后，我不能再使用大多数Python应用程序，包括pip（安装或卸载）。我在命令行中收到以下错误：

Traceback (most recent call last):  
  File "/usr/local/bin/pip", line 11, in <module> load_entry_point('pip==10.0.1', 'console_scripts', 'pip')()

    SSL_ST_INIT = _lib.SSL_ST_INIT

AttributeError: 'module' object has no attribute 'SSL_ST_INIT'

在搜索错误之后，看来pyopenssl的版本已过时，但是我尝试通过TGZ文件或easy_install手动下载安装pyopenssl18，但都没有起作用。

由于出现上述错误，我无法通过pip安装/卸载。有什么建议么？我想避免重新安装Python甚至操作系统本身。

再次尝试手动安装pyopenssl 18后，我注意到它的安装路径为：/usr/local/lib/python2.7/dist-packages

所以我去了那个目录，看到了一个名为：

的文件夹。

OpenSSL

错误中引用的

。我重命名了该文件夹，然后重新安装了pyopenssl，错误已清除。我访问HTTPS站点没有任何问题，因此这可能是被pyOpenSSL取代的已弃用的模块吗？
