Not able to install Python packages [SSL: TLSV1_ALERT_PROTOCOL_VERSION]

Answer 1

Following @Anupam's answer on OS X resulted in the following error for me, regardless of permissions I ran it with:

Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: ...

What eventually worked was to download a newer pip package (9.0.3) from PyPI directly from my browser - https://pypi.org/simple/pip/, extract the contents, and then pip install the package locally:

pip install ./pip-9.0.3/

This fixed my [SSL: TLSV1_ALERT_PROTOCOL_VERSION] errors.
