Hi,

I've been attempting to set up Pywikibot on my Xubuntu 15.04 virtual machine (which has MediaWiki 1.25.2 installed on it) and as compat wasn't working for me I decided to switch to core as compat is on the way out from what I've gathered by the Compat deprecation article on mediawiki.org. I have installed python (2.7.9) and python-pip but when I ran pip install -r requirements.txt from /pywiki (which I downloaded core to using git) I got the error:

Exception:

Can someone please help me with this error?
