Hundreds of "module not on sys.path" warnings

[Gabriel Hurley]

I installed bandit in a virtualenv (so I can easily dev on bandit) and ran it against Horizon (in a separate virtualenv because I also dev on that). I was presented with hundreds of lines of:

WARNING Module (<insert file path here>) is not installed in python sys.path. Names defined in this module may not be fully qualified.

I'd love to be able to resolve this warning, but no information is presented to me to do so. I don't want Horizon installed globally, and installing bandit in my Horizon virtualenv dirties both of them for dev purposes.

Being able to pass in a path or to add specific modules to sys.path when running bandit would be great!
