Unable to install any package through pip

For some reason I have issues installing new packages with my pip. I have an OS Sierra environment and everything was working fine before. Now either I use a virtualenv or not, I get:

Collecting requests
Could not find a version that satisfies the requirement requests (from 
  versions: )
No matching distribution found for requests

This is not only for the "requests" library but also for all the others (e.g. django etc.).

I have the latest pip:

 pip --version
 returns: pip 9.0.1 from /Library/Python/2.7/site-packages/pip-9.0.1-py2.7.egg (python 2.7)

And my python version is: 2.7.12

Moreover based on this article I checked if I can curl the PyPi website and I do get a response back.

Any idea what is wrong?

EDITED

I executed the pip install as:

pip install -vvv requests

and I get a detailed output of the error:

It may be worth trying pip install --ignore-installed --no-cache-dir pip to get an uncorrupted pip version (see here for the full issue).

The solution proposed by user1919 helped me to resolve installation of tox on lxc ubuntu container as the defualt pip version 8 doesn't recognize the correct url

I used:

pip install -v tox -i https://pypi.python.org/simple/
....
....
....
Successfully installed filelock-3.0.10 pluggy-0.9.0 py-1.8.0 setuptools-40.8.0 toml-0.10.0 tox-3.7.0 virtualenv-16.4.3

Thanks to @Klaus D. comment (proposed to add: the -v flag in the command), I found out that the URL for:

  http://pypi.python.org/simple/requests/

needs to be changed to 

  https://pypi.python.org/simple/requests/  (with SSL).

Executing this command worked fine:

pip install -v requests -i https://pypi.python.org/simple/

Alternatively you can change the pip.conf file as described in one of the answers here:

[global]
timeout = 60
index-url = https://pypi.python.org/simple
