React-Native "react-native run-ios"

Question

I installed a fresh react-native app.I keep getting the below error when I ran react-native run-ios

Incorrect hash:

eb7c61ff0c1c55cd85deb3c15f2731c14c787429 ?/Users/johndoe/.rncache/boost_1_63_0.tar.gz

I have tried react-native upgrade, rm -rf node_modules

Still doesn't work.

Also, is this a small part of a larger output? Might help to post the whole output. I had this issue because of a library file wasn't loaded in the past. — ReyHaynes

@ReyHaynes I tried rm -rf ~/.rncache and run the "react-native run ios" but the app is still not showing up on the emulator — Khadreal

try this one:

rm -rf ~/.rncache

then re-run it.

react-native run-ios

if it's still not showing the simulator, then you could try to add --simulator="iPhone 6s"

react-native run-ios --simulator="iPhone 6s"

Run this command to freshen up everything and pray twice facing the north.

watchman watch-del-all && rm -rf $TMPDIR/react-* && rm -rf node_modules/ && npm cache verify && npm install && npm start -- --reset-cache

Check this error using simulator app and real device.
Upgrade Xcode to currently latest version.

Otherwise use create-react-native-app. That way you can run app both device and simulator, which is great case if you don't need to detach your app.

I just resolve it, this problem is the version of boost wrong in start scripts.

Go to https://github.com/facebook/react-native/blob/0.56-stable/scripts/ios-install-third-party.sh and select the branch your rn version.
Drag to the bottom and go to the url such as https://github.com/react-native-community/boost-for-react-native/releases/download/v1.63.0-0/boost_1_63_0.tar.gz
Copy the download file to ~/.rncache, replace the old one.
Restart.

Done!
