Here's a screenshot of the post that helped me.

The whole forum has multiple different solutions which I hadn't actually tried, but this one is the solution that worked for me! Hope this helps.

Answer 2

As Jodie suggested above I tried the below and it worked well, for the benefit of others mentioning below steps which I tried in my mac to fix this issue

1. First, Kill all the server running and close your terminal.
2. Go to 'System preferences' -> 'Security & Privacy' -> privacy tab
3. Scroll down and click 'Full Disk Access'
4. Make sure you checked on 'Terminal' and 'Watchman'.
5. Now relaunch terminal and simply try running again it works!!

Answer 3

Use sudo command to run watchman.

sudo npm run test

This problem arose because you might be running watchman as root.

Answer 4

You're running watchman as root but the state dir, which may contain trigger definitions and thus allow spawning arbitrary commands, is not owned by root. This is a security issue and thus watchman is refusing to start.

The safest way to resolve this is to remove the state dir by running:

rm -rf /usr/local/var/run/watchman/root-state

I'd recommend that you avoid running tools that wish to use watchman using sudo to avoid this happening again.

Answer 5

I solved this, on linux by using the following commands on terminal.

$ echo 256 | sudo tee -a /proc/sys/fs/inotify/max_user_instances

$ echo 32768 | sudo tee -a /proc/sys/fs/inotify/max_queued_events

$ echo 65536 | sudo tee -a /proc/sys/fs/inotify/max_user_watches

$ pkill node

Then:

$ npm start

or

$ expo start (if you are using expo)
