pip：AttributeError：模块“lib”没有属性“Cryptography_HAS_SSL_ST”

所以每次我想用点子命令Ubuntu 16.04我收到以下错误：

 ~ pip3 --version              
Traceback (most recent call last):
  File "/usr/local/bin/pip3", line 6, in <module>

我尝试重新安装pyOpenSSL但是需要使用 pip 来安装，命令如下：

pip install pyOpenSSL

重现了相同的错误消息。请问我该如何解决这个问题？

答案1

就我而言，跑步

sudo apt install --reinstall python3-openssl

帮我解决了这个问题。
