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 pyOpenSSL

No 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

Collecting ipaddress

From cffi callback <function _verify_callback at 0x7f0d2e0419d8>:

Traceback (most recent call last):

File "/usr/local/lib/python3.6/dist-packages/OpenSSL/SSL.py", line 313, 

in wrapper

_lib.X509_up_ref(x509)

AttributeError: module 'lib' has no attribute 'X509_up_ref'

Could not find a version that satisfies the requirement ipaddress 
(from versions: )

No matching distribution found for ipaddress

The same error while trying to install a different module:

gabriel@E1-522:~$ pip3 install cryptography

Collecting cryptography

From cffi callback <function _verify_callback at 0x7fd515d659d8>:

I 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 autoremove

Made sure that /usr/local/lib/python3.5/dist-packages/OpenSSL/SSL.py was removed.

apt install python3-openssl -y

Then, pip3 was able to install again, and I lived happily ever after.
