Unable to install Python libraries

I am not able to install any Python libraries. I am using pip 9.0.1 and python 2.7. I am getting the following error:

EN-NishantS:~ 8417$ pip install presto-python-client
Collecting presto-python-client
  Could not find a version that satisfies the requirement presto-python-client (from versions: )
No matching distribution found for presto-python-client

On running with pip install -vvv I am getting the following:

Collecting presto-python-client

On Mac you can do sudo curl https://bootstrap.pypa.io/get-pip.py | python


I was having the same issue today trying to install Django.

I just re-installed pip. Get get-pip.py from https://pip.pypa.io/en/stable/installing/ and just run python get-pip.py in your virtualenv. That should overwrite the existing installation and update the SSL certificate.
