I’m currently running an expo project in development mode. Whenever I run expo start
or npm start
in the terminal I get the following logs:
$ expo start
Starting project at /Users/johncd/workspace
Expo DevTools is running at http://localhost:19002
Starting Metro Bundler on port 19001.
Tunnel ready.
Your native app is running at expb675c828acbb437095bc6218883f56bb://192.168.1.12:19000
Logs for your project will appear below. Press Ctrl+C to exit.
The expected results would include a QR code after these logs, but there is none.
When I visit the DevTools at localhost:90002 I see the metro bundler is running on LAN and a QR code is available. However, when I scan this QR code, it results in an error reading “No usable data found”.
-
I’ve tried checking for a Firewall (System preferences > Privacy > Firewall) but it appears to be turned off.
-
I have also tried uninstalling and re-installing
expo-cli
as well as the project and runningexpo start
again but to no avail. -
I’ve tried using
npm start
andyarn start
. I have also tried running the project on a tunnel. -
I created a test project using
expo init test-project
and successfully ran it usingexpo start
, so it seems this issue is only occurring on this project. -
I also tried running
expo start --clear
to clear the cache.
None of these have worked.
Any help is appreciated!
