This sounds like you're passing a -c option to pip telling it to
apply a constraints file, but you're attempting to install Horizon
from source instead of from a released package so it can't be
matched against the constraints list. The easy workaround is to
delete the Horizon entry from the constraints list you're using, or
consume a release of Horizon from PyPI instead of using a source
checkout.
