When we see errors like this, the cause is usually that you're on a corporate intranet that is doing something that prevents SSL from working. If that's the case you should speak to your IT department.

Other causes:

1. Github was down. Wait and try again.
2. Your SSL certificates are old for some reason. Try running pip install certifi and doing it again.

If none of those resolve your issue let us know.
