Stuck at "Installing Expo client on iOS simulator"

Please run expo diagnostics and paste the log that’s printed out along with your question or issue! Description

When I am trying to run an application on iOS Simulator nothing happens after “Installing Expo client on iOS simulator” log. This happens after the first successful run in the simulator. I delete the app from the simulator and close it. When I tried to run it second time (even on different virtual device) it’s not running properly.

Expected Behavior

expo start --ios
few seconds wait
open ios simulator
install the application on one of the screens

Observed Behavior

expo start --ios
few seconds wait
open ios simulator
then nothing happens, in terminal it stuck at “-” character like below

Starting project at /Users/user/app
Expo DevTools is running at http://localhost:19002

Hey @pirxie,

Can you try following this guide and see if that fixes it?


Hey @adamjnav what helped me was to install dependencies (expo as well) without sudo permission and in a different directory. By removing manually expo and yarn and reinstalling my projects runs :slight_smile: I wrote about this here

Thanks for the update and for sharing your findings with the community!
