一、AttributeError: module 'lib' has no attribute 'X509_V_FLAG_CB_ISSUER_CHECK'

NOTIFY_POLICY = _lib.X509_V_FLAG_NOTIFY_POLICY 1536
CHECK_SS_SIGNATURE = _lib.X509_V_FLAG_CHECK_SS_SIGNATURE -> 1537
CB_ISSUER_CHECK = _lib.X509_V_FLAG_CB_ISSUER_CHECK 1538 1539
AttributeError: module 'lib' has no attribute 'X509_V_FLAG_CB_ISSUER_CHECK'
解决方法:
pip install pyOpenSSL --upgrade
