You are using pip version 8.1.1, however version 8.1.2 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
This problem occurs even with administrator privileges.
open your cmd with admin priviliges. for that right click in icon and select open with administrator.
Upgrade PIP on your default python environment required sudo
, ie in Windows term, you must your start command prompt as administrator mode. In fact, this is not recommended.
You don't need to use sudo
/'Windows adminsitrators" if you setup virtualenv. It is python best practice to setup Python virtualenv , So you can separate the pip package required for individual project. For windows, it is similar setup .
Nevertheless, if you have decent PC with enough RAM, just install Virtualbox and deploy ubuntu. This way, your don't need to deal with windows python package installation/upgrade that overlook by developer (although all python package suppose to work out of the box) .
