Issue Resolving Dependencys with graphql-core

Issue description

Issue seems to revolve around resolving dependencys between these three libraries which according to there stated setup.py's should be compatible and install without issue with pip at these versions (i know that doesnt exactly mean there isnt an issue with the packages themselves potentially)

My assumption is something is weird with the graphql-core library and 1.1.0/1.1 is not being picked up correctly for some reason?

Thank you for any time you spend looking into this!

Expected result

pipenv install django==1.9 graphql-core==1.1 graphene==1.4 graphene-django==1.3

should lead to the packages graphql-core==1.1 graphene==1.4 graphene-django==1.3

installing with the expected versions

Actual result

pipenv install

Warning: Your dependencies could not be resolved. You likely have a mismatch in your sub-dependencies.
  You can use $ pipenv install --skip-lock to bypass this mechanism, then run $ pipenv graph to inspect the situation.
  Hint: try $ pipenv lock --pre if it is a pre-release dependency.
