@user1543915 - Yes. If you're in the venv, you should only do things in the venv so you don't screw up your host environment (i.e. the whole point of using a virtual env in the first place). — ggdx

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

in the (venv) dropbox.com/s/i435ikd7t0q4uy4/CaptureS.PNG?dl=0
this error is due to the proxy settings of your system.pip is trying to download the package via proxy and it fails to do so.

i solved with the following command, and it worked for me: sudo su root sudo su root apt-get purge -y python-pip wget https://bootstrap.pypa.io/get-pip.py python ./get-pip.py apt-get install python-pip
