Can't install pdfminer.six on Windows 10

Question

On my cmd window, I typed

pip install pdfminer.six

and it gives me these errors.

I use Python 3.6 on Windows 10. What should I do? Is there any way that I can install this package without using pip? I want to use this link: https://pypi.python.org/pypi/pdfminer.six/20170720

I'm pretty new to programming, so I don't know much.

This is a proxy problem, as the retry-error-message tells you. Your pip does not connect to the internet through the proxy.

Try pip --proxy url:port pdfminer.six with url:port beeing your proxy, e.g. proxy.example.com:8080.

If this is not working, try using another internet connection without a proxy to install packages via pip, or have a look at this thread, which has more answers regarding pip and proxy.
