Exp-cli and Exp xde Packager hanging/stalling right after "Dependency graph loaded." step

I just started having trouble with this on my work laptop. It was working fine up until Friday…

I’ve tried a number of things, including all of the steps listed here: How to clear the Expo and React Native packager caches (Metro, Watchman, Haste)

Recently noticed in ~/.expo/log :

{
"name":"expo",
"hostname":"my-host-name",
"type":"project",
"project":"path-to-my-project",
"level":20,
"tag":"expo",
"msg":"No packager found for project at path-to-my-project.",
"time":"2018-05-07T21:13:00.878Z",
"v":0
}

Not sure what to do next!
