AttributeError: module ‘lib’ has no attribute ‘X509_up_ref’
主要原因是系统当前的python和pyOpenSSL版本不对应
解决办法
卸载再重装pyOpenSSL
pip uninstall pyOpenSSL
pip install pyOpenSSLNo matter what module I try to install via pip3 install I always get the same error :
AttributeError: module 'lib' has no attribute 'X509_up_ref'Have no idea how to solve this one. Anyone had this issue before?
gabriel@E1-522:~$ pip3 install ipaddress

No matching distribution found for cryptographyI run Ubuntu 17.10 . I have both python 2.7 and 3.6
Thank you.
This is what resolved it for me:
as root on Debian:
apt remove python3-openssl -y
apt autoremoveMade sure that /usr/local/lib/python3.5/dist-packages/OpenSSL/SSL.py was removed.
apt install python3-openssl -yThen, pip3 was able to install again, and I lived happily ever after.
