Trouble installation pywikibot?

[nichtich]

Tested on Ubuntu 14.04 LTS:

$ pip install wdmapper

Could not find a version that satisfies the requirement pywikibot (from wdmapper) (from versions: 2.0rc5, 2.0rc5, 2.0rc3, 2.0rc4, 2.0rc1.post2, 2.0rc1.post1)

Solved via installing pywikibot like this:

$ pip install pywikibot==2.0rc5
$ pip install wdmapper
