I'm not able to install any pip libraries and I'm getting error.

pip install --upgrade pip
python -m pip install -U pip
pip install flake8

Error in the console

Is this still happening?

Not anymore, I installed the pip 8.1.2 and I was able to install the other pip libraries

Hi,

Check your office N/W, I had an issue with my office N/W I was using and I was not allowed to install. I connected to a different office N/W and changed my proxy settings too. I am able to install now.

Thanks,
Lokesh
