I tried "watchman watch ~path" , "sudo" & "chmod" but they didn't help me.

Can someone advise me please?

Answer 2

cd AwesomeProject, and execute chmod -R 777 * it still failed. after i give the permission to the top dir, it work! chmod 777 AwesomeProject

Recursively changing the owner of the relevant directory (whatever is referenced in the error) fixed it in my case. But before I tried that, I tried 777 perms, and that worked to. But 755 was liberal enough once I fixed the owner. – Tigre

Answer 4

I've tried all the above and none of the solutions worked, try this:

type watchman watch ./

in the top directory of the RN project you want to run,

then again react-native run-ios
