@therovermind Is this happening in a fresh project created with create-react-native-app? Could you fill in the information in the issue template (especially any error messages, if you're getting them, the environment and if possible, a reproducible demo). This would help the issue get resolved much more quickly. Thanks!

Hi, possibly related to https://github.com/react-community/create-react-native-app/issues/234. This comment was helpful for me: https://github.com/react-community/create-react-native-app/issues/234#issuecomment-313849888

Hi,

I have the same issue, no qr-code generated but the project was compiled.

[brentvatne]

try this https://github.com/react-community/create-react-native-app/issues/234#issuecomment-313849888

I had the same problem, no qrcode generated while npm start command,
The terminal itself mentioned to either install watchman or run the following commands:

sudo sysctl -w fs.inotify.max_user_instances=1024
sudo sysctl -w fs.inotify.max_user_watches=12288

These commands worked for me. :-)
