I have the same issue with react-native 0.13.0. @sapphirezzz: What version of node are you using?

[jpapillon]

@sapphirezzz : Check my comment on this issue.

@jpapillon Mine is v5.0.0 . I have fixed this by using (JS_DIR=pwd; cd node_modules/react-native; npm run start -- --root $JS_DIR) . I put the .js file and node_modules in current folder .
