Getting "cannot detect ios-sim on path" warning

I'm using webstorm to build a phone gap project and I'm getting the warning "cannot detect ios-sim on path" on my iPhone run configuration. The sim is definitely installed--I'm able to use the run configuration to launch the app in the sim. But for some reason the warning persists. I've tried resetting and reinstalling pretty much everything to no avail. The fact that it runs means I can still do work, but the error is still frustrating.
