There's some weirdness with the travis boxes where they don't seem to be able to find cached modules... Per https://travis-ci.com/randytarampi/lwip/jobs/183637295. ``` npm WARN prepare removing existing node_modules/ before installation npm ERR! code MODULE_NOT_FOUND npm ERR! Cannot find module '../pack.js' ```
