Estou com este erro, após instalar reactnavigation e suas libs, e tentar rodar um novo metro bundler:
(node:31976) UnhandledPromiseRejectionWarning: Error: Metro Bundler process exited with code 1

(node:31976) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag --unhandled-rejections=strict (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 932)
