Watchman won't let me start any of my react native projects after i updated my mac OS

Question

This is my first time asking a question so please bear with me if i’m not asking according to the standards but ill try my best.

watchman warning: opendir(/Users/abdi/Library/VoiceTrigger/SAT) -> Operation not permitted. Marking this portion of the tree deleted To clear this warning, run: watchman watch-del /Users/abdi ; watchman watch-project /Users/abdi

This is the error i'm getting every time i try start any project, even the ones that i created previously.

I tried the following:

1. watchman watch-del /Users/abdi ; watchman watch-project /Users/abdi
2. Giving watchman full-disk access and restarting
3. Moving my project to root folder (/Users/abdi)

This is what i get when i run watchman watch-list { "version": "4.9.0", "roots": [ "/Users/abdi" ] }

Please help.

Answer 1

I found solution. After giving full disk access use watchman watch /Users/$USER/.... to watch your project instead of watchman watch-project /Users/$USER/....

Thank you for the tips, I ran watchman watch . at my project's directory and it solved the problem. – Mayest

Answer 2

Bit late to the party, but to me the following worked

1. Shut down the metro server / simulator (if it's running)

2. Turn off and clear watchman cache

   $ watchman shutdown-server
   $ watchman watch-del-all
   

3. Start your react-native project (i.e. react-native start, expo start, etc.)

There's no need to give watchman full disk access (nor should you)

Answer 3

You need to grant full disk access to watchman to allow it to watch the locations you've asked it to watch.

Go to 'System preferences' -> 'Security & Privacy' -> scroll down and click 'Full Disk Access', and then check 'Watchman'.

After changing this, restart your laptop.

Thanks for your answer Wez. Unfortunately that doesn't work for me. I have also tried everything suggested in those discussions but still have the problem. – Friesian

Nothing works, hooray! – Nadeau
