I have tried installing without pip but I couldn't get that to work either.

I'm pretty sure its to do with company firewalls but can't seem to get around them.

Thanks

I've seen this error before, it is usually caused by being behind a corporate proxy, or you have been pwned.
Assuming its the proxy, you need to figure out what your https proxy is and add it to the pip command like so:

pip install requests --proxy=https://my_proxy.com:xxx

where xxx is the port of your proxy
