React Native Expo Failed building JavaScript bundle

Question

After installing a package and running react-native link. I get the following error message in the logs of exp start when I try to launch the simulator on Xcode:

Failed building JavaScript bundle.

There's 0 additional information and my project runs but this errors show up in the terminal and the get the simulator stuck at 0%...

I have no idea how to fix this since I'm unable to get any additional error nor information, just this ****** error message.

@MarouenMhiri Thank you whoever you are you're the angel of my day. You saved me seriously I was in the process of remaking a new expo detach project and then I would have had to rewrite all my code etc... Anyways THANK YOU — Hugo

Just a minor typo tho it's "rm -rf $TMPDIR/react-*" for anyone reading this later on. — Hugo

Clearing the cache via expo start -c AND restarting the bundler by pressing R in the terminal as Hameed suggested helped in my case

In my case I was trying to start an app on the Android emulator. Changing the connection mode to tunnel from LAN on the server console allowed the app to build.
