how to fix watchman error

When building React Native apps on Linux, you might get this error at some point:

The user limit on the total number of inotify watches was reached; increase the fs.inotify.max_user_watches sysctl

Here's how to fix it:

You will need administration privileges at some point!

1. Check for the current value of max_user_watches

        cat /proc/sys/fs/inotify/max_user_watches
        
2. Set max_user_watches to a number higher than the current value

        sudo sysctl fs.inotify.max_user_watches=10000
        
That's it! Now make sure it was set correctly:

        cat /proc/sys/fs/inotify/max_user_watches
        
Enjoy!
