import backports.ssl_match_hostname
ImportError: No module named ssl_match_hostname
I've tried other solutions suggested such as
pip install backports.ssl_match_hostname
but:
Requirement already satisfied: backports.ssl_match_hostname in ./yt-x86_64/lib/python2.7/site-packages/backports.ssl_match_hostname-3.4.0.2-py2.7.egg
I am using Ubuntu 12.04 LTS
