Answer 1

In order to install a specific version of pip , use the command
pip install pip==8.2.1 after activating your virtual environment.

And , if you get SSL error like this

Could not fetch URL https://pypi.python.org/simple/pip/: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:590) - skipping.

Then , first you to have get the latest pip , then only you can install a particular version of pip.So, to get latest pip, execute this command

curl https://bootstrap.pypa.io/get-pip.py | python.

Now try this pip install pip==8.2.1
