title: Everytime I try to install a package using pip it shows an error
body: <p>Installing jupyter notebook. Everytime the same error occurs. And the error is the same if I install any other package too. I am currently using python 3.6.5 version which is the latest one. I have recently downloaded python and my windows version is 10.</p>
